I think you might have some problems with Taka.

Not necessarily. It helps a bit on Koshkas and Ringos and quick heroes sometimes. I think better aim and prediction is better. BRB is a punishment for bad positioning, sniping, and making melee bruisers regret standing in one place too long. I'd say the power of Shatterglass+BM is better, and makes up for any extra milliseconds you might gain with a Frostbite. Often your thunderstrike or rocket leap will hit a hero first, wasting the frostbite effect before you can use your BRB.

Erm, this is weird, but perhaps more diversity. I hope I'm not going to get argued with too much or open a can of worms. Vainglory is new and can easily create diverse heroes without seeming like they are pandering and without controversy. How about a female Laner?
