Hey I got suggestions!
Could you make it so that the minibases can't be captured? This would be big change but I think worth it. Atm. they are bit too easy to destroy and end game will just be annoying backdooring.
You could make them have like 4x more hp than what they have now and after destroying then its lost and no creep bonuses.
And make observatories less imba

I think that maybe something like when you control it you can use "Dust of Appereance" (Change name

) in it which actually reveals the area it now does. Or just give it Reveal spell with large radius that can be used from it. Maybe for 10-15 seconds reveal? And 1.5min cooldown. Since its bit too revealing the way it is now.
And one balance thing: Why can crypt lurker keep my stun over 8 seconds?
And complete rework on items to more like in dota would be nice but too much job I know. And this current system is good because you choose items you want for your playstyle. Downside is that most people just always get the same combo for every hero they play.

Possibilities with current item system are quite small.
Btw. I love goblin merchant shop items

Its fun to buy cheap good items. But I don't like that there are too few options later game.
And one more thing: LATEGAME IS STILL AWFULLY BORING!
I love this maps early game. Its wonderfull. New skills, items. Late game its just getting most and best items and hoping you are better than the enemy.
Its really boring. Others in my games said that too. I have many times left just because the match never ends. Making minibases once destroyable would help this a bit.
I'd like to see a command like -endgame ;D
It would give all players defeat and say "Host decided to stop this game now because of too much boresomeness"
EDIT: MY ITEM SUGGESTIONS.
Keep goblin merchant. Acesories shop (mountain king) could stay I think.
Remove both armorys. Well maybe keep keg ale and the two items next to it.
Remove secret shop (and the items ofc

)
New shop looks promising. But the flag items could be removed.
And maybe the system of upgrading boots of speed and gloves of haste isn't very good idea. Something similar to dota could be nice. Like one boots only and few upgrades of it depending what you want.
Orbs are too expensive. Rarely anyone bothers to buy them. Make blank orb 400 cheaper and they maybe could stay
Well thats how I would make it.
More stuff: Helicopters in the air skill could be better. Its kinda useless. Maybe add something like faster bombing in the autocast skill while in the air or something cool?

Or did it already increase movement speed? :/
And teleporter. Could something be done about it since so many times its used for ganking? Maybe something like 6 seconds unmoveable after teleporting so that you can't run after the enemy right away? Or 30% slow or something? Could be really nice.
