Also I played a semi-try hard game with teams of 5 where each team trilaned and there was a ra in the game.
http://hondamage.com/eqLiBm/ranked/42312571We had plague+myrm+flint vs. voodoo+witch+zeph in their short lane. Our ra was solo against their valk and he still farmed well enough with his passive skill. I told them at the middle of the game, when we were raping them, that they should've had zeph solo vs. ra.
That would have made a very entertaining lane to watch.
I think he could be used pretty nicely in competitive play where you know they're going to do a solo side lane of pharaoh/kraken
