What is, in your opinion, the heroes that require the most skill to use?

My vote goes to Invoker and Meepo.
Invoker has spells for numerous situations, and using them in synergy with each other is very hard to master.
Meepo is obviously hard due to the micro control.
Other hard heroes to master are Chen, due to the multiple creeps he has to control.

What are your suggestions?

I think any 1 who ever played wc3 ladder can play chen or meepo without any probs

i think mepo

cuz u have 4 heroes ^^

i think u don't need 2 posts to say 1sentence .

@Snowflake

cuz i can't edit .

should try 1letter per post then, ur level will grow faster then.

I don't think Chen is hard to "master".. Just make groups of the creeps and same with meepo.
But if you don't then these two are very very hard to master.

Uhh... Meepo?

I suck when it comes to grouping a unit.
It's because my number keys are bound in the inventory slots.

On topic:

Invoker.

He has multiple spells.
All you need to do is master the Q, W, E thingy. :))

And know all spells out of your head 8-)

@drunkpunk just QW EMP TORNADO > CHAOS METEOR > ALL OTHER INVOKER BUILDS
