the one that runs on warcraft client. do u think anyone still playing it?

dota 2 changed too much until I cannot adapt. lol

can I ask a few dota 2 noobish question?

1) smoke deceit can hide heros from zeus ulti?
2)smoke deceit is so cheap why do people don't use it more often?
3) is huskar imba? it definitely is the way I see it. his ulti has low cooldown, and he hits like a truck. and your hp will drop faster than his.
4) is centaur shit now ? the ulti has changed , no more strength gain.
5)how can I debuff ursa other than diffusal blade?
6)are some heros more power than others? I realized that some heros get picked over and over and some heros never get picked (hot pick : PA, ursa, invoker, Legion fucking commander, huskar, pudge, mirana, drow ranger, slark. And heros that never get picked like Doom, winter wrymn, goblin shredder, lich) Do these hero get picked less because they are just underpowered?
7) why is the opposition team always so imba?
8)I've not seen anyone buying guinsoo... that item gone ?
9) what is the purpose of planting tree from ironwood branch?

more when I can think of

against AI or player? garena?

fuuu so garena still got ppl play dota 1. cool.
