Battlegrounds has a new cat hero! I played a couple games with Mr. Bigglesworth yesterday and here are my initial impressions of him:
His hero power is super fun to play with if you can use it a couple times in a game. I think the discover aspect is a little underpowered and maybe that number can be tweaked to adjust his win rates once there is more data (i.e. discover 4 minions instead)
He feels like a combination of playing Patchwerk without the HP boost and Eudora without the consistency. You're essentially doing nothing with your hero power for most of the game and you never know when your hero power will actually activate. I think it's a fair trade-off since theoretically you could end a game having "dug" 6 golden minions from your opponents and discovering a minion from a tier up 6 different times if you happen to discover a golden minion each time from your hero power.
The unfortunate thing is that most people who die in the early game don't have super strong minions to begin with, so often your hero power for the first couple of deaths don't provide you with a huge power boost anyways
Because of his inconsistency I think he will be a Tier 3 or Tier 4 hero in terms of win-rates but I think you will definitely see him from time to time at all MMR levels just because there is always a chance he can snowball and win games with his hero power.
