If they meet up for bosses. There'll be problems. Paladin has 3/4 debuffs on a mob almost constantly, with another 3 depending on situation.

Flash, Scorn, Rage of Halone and Fracture will be up almost all the time. With Pacification/Stun/Silence being situational. One tank has just made more than 10% out of the total limit right there. Out of 24 people. This isn't going to work, assuming a full setup trying to down one boss.

Either content will have to be made such that alliances won't be hitting the same targets all the time, or the cap will have to be worked around somehow. If debuffs get overwritten, hrm, what to overwrite? That critical pacification? Maybe the stun - that won't be needed. Flash - tank can just take more damage right? If Summoners are going to be screwed, the entire alliance will be having issues with content. No having your Whm Aero for more damage. Maybe we'll get total immunity from all debuffs, so stun/flash/rage of halone/etc become moot points so they won't need to be applied.

It's not a whine, just a - seeing that if this is exactly as stated, then more than just summoners are going to be hurt by this.
