I think this HUGE nerf is going to hit hard, because (rightfully so) people will want to changerace from DL cause FS is simply unplayable, low range, really bad atk speed, most of the time positioning buffs out. (you forget on phoenix when it was only FS, we had CTRL bug, and let's be honest dl was a disaster on phoenix).
The 2 problems i see hit straight into the Castle Siege:
1. Most will change, you wont be able to find DLs or get underleveled ones, so no summon.
2. DMG-DLS are gone from CS as of now, their dmg is inexistent with 45% nerf dmg, then -50% on CS server. So we are back again to the all DLS go stomp meta with a chaos overall and spam horses. Hiu, so skilled
