Darzar
-can his life regain/still ability be added to the Mask of Death effect items? If so, that could be a problem lategame
-imagine a lot of strength/defensive items on this hero plus his abilities to regain life
-the trick might be not to have this hero get close/hit you which doesn't work against some other melee heroes too well
Zanedar
-do items that give attack speed help his attack speed abilities? At least, his ability is zone dependent
-that Naze is really draining the whole of your mana in mere seconds; gods, doesn't this lich have a death timer? It seems he revives after 0-1 seconds/instantly
-imagine Porthole Jumper on this hero

basically two teleport spells
Grogmar
-his Berserk spell can leave him stuck between doodads (happened in the southwester wall of the zone that surrounds Hantu... Of course, using the spell again frees him but, that's not a good idea; what if you don't have mana that time when you need to?
-his name in Infernal mode is Ganas (not sure if intended); also he has an advantage against Atok because he has chaos damage
Kigami
-has very many assault and dangerous spells two of which may also be used to evade and get through walls; plus Zelous makes him invulnerable for some good seconds; some damage reduction I think would be adequate
Bourne
-Vorpal Slash is way too powerful; besides increasing damage and width; it can be cast through walls from quite a high range
Malari
-isn't the Blink's range 1400 too much when the hero also has a return blink ability?
-30 seconds invisible and able to attack? I guess at least one enemy is forced to have a Gem of True Seeing
-this hero is extremely powerful; imagine a match with this one and Kigami in the same team
Darrow
-becomes Beowulf. Intended?
-Frenzy is very powerful and has not such a big cooldown; maybe instead of 300% of agility+strength; maybe either just one of them or 150% of both?
Melissa
-needs balancing
-Ghostring is totally overpowered and it's a passive ability!
-Desolation should not give agility if just any unit is killed because the hero will become too powerful in quite a short time; in late game it would be very easy for this hero to kill multiple enemy heroes; not only does the hero get bonus damage but also armour and attack speed!
-on top of that, the ultimate give even more bonus damage
Hale
-I think Apocalypse might be dealing more than 140 damage from the second wave onwards
-Fire Blast also stuns so it would be better if it would deal less damage since it's AoE based
Naze
-overpowered mana leech spell
-using Dark Veil and the charging nova spell is quite a killer strategy; basically you appear out of nowhere and kill/critically wound everybody+slow
Emerald Boa
-this hero's spells cost quite a lot of mana; that's good because they can't be spammed like other agility heroes can
-Paralyze Gaze is a bit too much with that 100% evasion when the enemy gets stunned, slowed and damaged; maybe less evasion? I mean in teamplay it's good because enemies can use magic on Boa but in 1v1 it's not that easy
Light Bringer
-not sure if the ultimate (1000 damage) is too much or not
Tygore
-Vigorous Attack pretty Op with items
Mauna
-Consume Warmth can be used on the hero to create lava elementals
Mozo
-12 seconds a frog? That's kind of like dying at least 6 times; late game that is super powerful
-Mystic Wave + Torment Ward in 1v1 seems pretty powerful too; might be required to increase the mana cost of Mystic Wave
Nalini
-basically if you're near this her when multi arrows are shot with Heaven's Twilight on, you're kind of dead
-the ultimate triples the damage of every friendly spell does it not? That's a win for that team in said battle, I guess
Adora
-range too big? 1400... this is really bad when that hero and another fight and they reach low hp and Adora runs and then shoots from a longer range; I suggest lowering it to 700 or at least 800; imagine how towers fall without hitting the hero or how enemy heroes could be hit over/through the magical barriers that appear around Hantu sometimes; or how the hero can abuse attacking Hantu; set the attack to siege mode=/=homing projectile?
-after this hero dies, the vulture effect(?) remains there until the hero revives
Aeolian
-can Colossal Cyclone be escaped with spells because the duration is quite huge?
Xerar
-a really interesting hero; not very easy to use but skilled players could surely turn this one into a super assassin specially in midgame-lategame
Miraculous
-Guardian Appearing says it makes the Ent appear as Guardian of Nature; it's a bit confusing; it just replaces the Guardian Spirit with the hero
Amberella
-methinks, Adaptaion lasts too much and doesn't require enough mana
-Tidal Wave's hotkey text is Q instead of D; this spell and that Vortex from the Far Seer model hero are quite powerful
