Wardens are supposed to be the heavier, the tankier class of this new Teamfight Tactics set. Sadly, they just feel thin like a sheet of paper. Overall, we were pretty disappointed with them, that's why we're super happy about this buff. Will it be enough? It remains to be seen...
Regarding the Shadows' nerf, we just feel a bit concerned because it just feels that Master Yi is the only real reason why this Trait is actually strong. At the end of the day, it's probably one of the hardest synergies to pull off since it requires at least two Tier 3 units. Even with that, it appears super weak, at least until you get Yi. Nerfing or buffing it doesn't seem to be the solution, at all.
