I have been trying out Wurt and I have got to say that her play style sacrifices to much for what gain she gets to help a team or playing alone.
Solo stand point as playing wurt for a long period of time:
1. she kinda can't get gold as plentiful as using pig king.
2. Trinkets have no use to her and she can't use the chess piece trinkets. Would be fine if the merm king took them.
3. Merm king is underwhelming in his loot pool to just keep Wurt alive with food and the occasional tentacle spot.
4. The merm king buff is ok, a suggestion would be a small damage buff to Wurt to be similar to other merms.
