Considering that you leave the other side 9 more levels to destroy your team because you want to use his H10 damage helix, that’s a fair trade.
No matter how hard you try, the most you can pin down is one person at once due to lack of AoE and large CC unless you can somehow knock one person into another. This is one limit Boldur faces. Out of the 2 sup 1 carry comp (Gal, Montana or Galilea), Boldur is probably the worst choice because he won’t really be able to protect the backline if they get jumped on while Boldur is engaging.
So yeah, if you somehow get all the gear and snowball all the way to level 10, the other side deserves to lose. Way better than dealing with char who spike to almost the peak starting at levle 3.
