The heal casts itself because it would be annoying to switch to the healer every second attack.
Right onto my list of stuff for you to fix:
Mana issues: here's an example. Healing wave costs 800 mana while chain heal costs below 100 mana.
The following moves have a rank after their name but others don't:
Chain Lightning, Feral Spirit, Shockwave, Stormstrike, Sinister Strike, Blizzard, Arcane Intellect, Arcane Blast, Rain of Fire, Trueshot Aura, Lightning Bolt (on the tooltip)
Moves that should not be there (not counting the fact that healing classes don't use damaging moves):
Bloodlust - Shamans don't have that.
Feral Spirit - Yea the original Wc3 shaman has it but not the WoW one.
Fear - Every warlock knows that even when a mob is attacking you, EVEN WHEN YOU ARE DYING do not use fear. Fear may send the mob to the next mob pack wiping the raid almost definitely. Better you than the raid.
Trueshot Aura - You have only one hunter and no one else gets (or is supposed to get) bonus from it. Just increase the hunters damage and don't put in auras.
Spelling mistakes and tooltip tips:
The file name is Naxxaramas. Not that important but still
Defend - Tooltip says it reduces the warriors movement speed by 0%. Remove that bit.
Taunt - ... the closest 1 enemys... enemIEs oh and change it to the closest enemy.
Devistate - It's Devastate. Either this has too many spaces behind "causes threat" or Shockwave does. Either way use ctrl space to go to next row.
Power Word: Pain - Tiptool no sense. make Oh and add damage to the tooltip.
(Use) Power Word: Shield - Remove Use from the beginning, add a tooltip. Also when it's activated its name is Unbreakable Will with, again no tooltip.
Sinister Strike - It has a Instant written under the name.
Shadowbolt - Add damage to tooltip.
Coruption - There's two r-s in Corruption. And... 150 damage over 24 secs WTF?!
Steady Shot - Add a tooltip.
Volley - Add a tooltip.
Multishot - Add a tooltip.
Healing Wave - Add amount healed to tooltip.
Lightning Bolt - ... for. <- For what? It's in the very end.
Missing hotkeys:
Stormstrike, Power word: Pain, Windfury Totem, Slice and Dice, Stealth, Kick, Icelance, (if you are very persistent on keeping it in) Fear, Corruption, Chain Heal, Steady Shot, Volley, Multishot, Healing Wave, Lightning Bolt, Shadowbolt, Devastate.
Icons:
Shockwave- change to shockwave, it fits the style
Stormstrike - Passive icons on activated abilities and vice versa is bad.
Power Word: Pain - Use something better.
Arcane Intellect - Give it an activated ability icon.
Arcane Blast - Change to Detonate.
Shadowbolt - Seriously. It's Shadowbolt not trident throw.
Corruption - Change to an activated ability icon.
Chain heal - Nope, not feeling it.
Healing Wave - Change to an activated ability icon.
Lightning Bolt - Yeah, right.
Ability changes:
Shockwave - It actually does the shockwave arooouuund the warrior. And it doesn't stun, it slows. Base it off Frost Nova.
Power Word: Shield - This activates both the priests... unbreakable will :/. Oh and it doesn't wear off with time. Or it does with too long time.
Slice and Dice & Sinister Strike - No combo points now? Oh and Slice and Dice activates berserk?
Stealth - Stealth shouldn't cost mana.
Kick - Make it auto use it only when an enemy casts a spell cause it's a waste of mana otherwise.
Arcane Intellect - Make it an activated ability buff because i don't feel comfortable with "Increases targets Int by 30"
Multishot - Make it an activated ability.
Reincarnation - Increase it's cooldown. Oh and despite the tooltip he reincarnates with full health and mana.
Also mind putting all hotkeys to Q,W,E & R? Much thanks
That's all for now.
