She seems to be useful most everywhere may have to drop a hero you've grown fond of and swap her in for PVP, but that's not anything unusual for this game, happens all the time. But fitting her into your lineup depends upon your current place in the CC world, if you have every hero or just a small smattering of decent ones. So take the opinions of those who say she's not all that special with a grain of salt, more than likely they have every hero and have their synergy in place- nothing new there as well. New heroes basically have to be Lavanica-esque to impress the....well, CC snobs lol.
For high end upper class players that can spend $20-100 for new/newer talents- zealous drive and sacred light (at the moment until a new talent comes along) seem to be favored. But for players that don't buy one can get away with zerk, Stone skin, scatter, bulwark. No, a few of those not optimal but take what you can get, ZD and SL don't show up like the others I mentioned, opened about 50 level 5 talent chests came across two unholy pact and one sacred light, about five SS around the same for scatter, bulwark, zerk.
Fun hero nice change of pace game changer for a brand new account.
