I have it, played few games, meh. It's fine but I guess I play LoL too much to change to Dota now.
Plus, I suck even more than in LoL ;_;

purely cosmetic changes that you can buy with real money and a game where people insult other people for being russian or not russian?
wow, sounds familiar

been playing a bit, took me a while to get used to the gui and graphic changes, actually still getting used to it, 6 or 7 years of warcraft3 dota, i guess i should expect it.

some aspects are better, some im not so happy with, overall, im enjoying it, it just feels the same as dota1, which im bored of lately

That'll be the case since they said they're doing a port first and changing second :v

Added some nice recent competitive matches to the OP, definitely recommend watching them, both are action packed and show incredible teamwork in balanced games.

1 key to rule them all
Also, how does one get a beta key for it nowadays?
I already have one.
Is their referrer keys?

As far as I know, beta keys are (almost never) distributed nowadays through http://store.steampowered.com/app/570/

But if you actually want a chance to get in as well as a bunch of cool cosmetic items to go along with it you should buy in here for 40$:

I just so happen to have a spare copy of DOTA 2 on my steam if anyone wants to trade for it. Not quite sure what I want though :S

Can anyone suggest me a good invoker playstyle,I usually go exort quas which dominates early game but I seem to do very low damage later on.

wex/exort is still very good even after the emp nerf.

e: actually just keep going quas/exort and use forge spirits to make sure it doesn't get to lategame. PUSH PUSH PUSH PUSH

With invoker it depends on what you want to do.
If you want damage you go Exort > Quas. If you want utility you go Quax > Wex.
If you want push you go Wex > Quas. ( Forge spirit and alacrity, use it on the siege minion for maximum pushing. ) At about level 16 you can pretty much do what ever you want with him.
