Wes's transition into DST has brought some rebalances, but i think they just make him better at group starving.
In single-player, Wes could only use his pile o' balloons to craft a single all-purpose balloon which will stay in place and Float, Float, Float and Float whenever needed. This makes it much harder to multi-task, as all balloons crafted by Wes will do whatever Wes commands them to do next - There's no distinct balloons that would Float while Wes does something else.
Now in DST this was changed. Wes can now use his pile o' baloons as a CRAFTING STATION for distinct balloons with different jobs. He can create a Balloon Floater, who will float endlessly, a Balloon Floater, who will float endlessly, a Balloon Floater, who will float endlessly and a Ballon Floater, who will actually float whenever needed, which is pretty much always so he will float endlessly. This change makes multitasking much easier. No more balloons floating in unison - now you can have separate balloons floating while Wes is busy doing other work! This helps when gathering materials.
In vanilla, balloons used to pop when you hit them. HOWEVER, in DST you can pop them anytime and get nothing back from it! My only criticism is that when someone else pops your balloon, it's gone and you get nothing for it. That kinda sucks.
Overall, i'm very glad Wes was rebalanced for group play. This makes him a much more attractive character, even with his low stats. Plus, crafting a new balloon doesn't take HP anymore! In vanilla, balloons used to not take HP either. I'm glad this was changed too.
