My opinion on Xerath in his current state in the meta.

Fun as fuck.

If you guys haven't tried playing Xerath already, I really do recommend it. The new frost queen's synergizes so well with his ultimate it just gives me goosebumps. Wait for the ghosts to climb to the enemy, then shoot all 3 ultimates off as they are moving at a crippling 20% MS or whatever it is.

The new blue trinket also works wonders with Xerath's kit.

And if you are worried about the frost queen's nerf, don't be. Going from 60s to 90s does not hurt Xerath, as he primarily only needs it for his ultimate to finish people off. This might in some ways help even, cause now alot of other champions besides you won't be abusing it as much. Thunderlord's nerf will not do much against Xerath either, as he does not typically proc Thunderlord's easily in the early game anyways. Infact, it helps for the most part, because the main use of Thunderlord's on Xerath is gonna come into play later in the game when hes able to easily and efficiently land a E-W-Q on an opponent through the fog of war.

My only recommendation is to make sure Rengar and Zed are banned. Rengar will be getting nerfed too, so he shouldn't be as much of a threat. Talon might be an issue but lets be honest, no one plays talon right now besides Haunt. Fizz can be dealt with very easily, just get barrier and poke him from afar. Every other matchup is easy.

Enjoy your fun freelo boys.
