		- COMBAT_TEXT_UPDATE: which gave no extra information
		
		After the first 4 increases, I had 1 UPDATE_FACTION.

		Overall, UPDATE_FACTION is called less often, I'll register this one to rescan factions.
		
		Nope, bad, UPDATE_FACTION is triggered when expanding/collapsing categories => deadlock
		Only solution is to prevent subsequent events from triggering a scan.
		=> No scan if event was triggered less than 3 seconds ago. Not nice, but Blizzard really doesn't help here..
