Is your time 5 minutes slow?
Maint started on time for me, and I haven't heard of 5 minute time zone shifts before.
The map server goes down at the right time or a few minutes later, typically. However, changing map zones or logging in require access to the character and login+character servers respectively (for the former, when people are kafra warping around, or moving through eden to warp to Pront or elsewhere, you'll see via Friends lists or Guild notices that X character has disconnected, connected, repeat). Early character server shutdowns just screw over the people who need to change zones in the last (apparently) 8+ minutes before maint.

As for Release... It sounds like part of the problem is that you can cast other spells (including more Reading Spellbook) while the Reading Spellbook prompt is up. (e.g. you can cast Read Spellbook, target a monster or enemy with CR while the prompt is open, re-cast Read Spellbook, choose a spell while 2nd RS is casting, etc etc.) Can't we just disable that feature, in the same way it's disabled for Teleport?
Also, how are endless RSs AND Releases going off? During RS's cast time, you can't cast Release... Sure, you can cast it between RSs, but there are still delays during the cast time, no?
In any case, crippling a class for PVM because of some WoE issue is a little one-sided. Make Released spells in WoE deal half damage or something. Just don't cripple my pure PVM warlock because of some stupid WoE problem.
<edit>@Tenmuki, yep, Kounosuke is me~ That's why I couldn't get back, apparently... Sorry for the sudden disappearence Q_Q
