as vaguely also discussed here
yes inq now has a minor self mana regen. i still miss the minor group mana regen aura myself. would also be happy to have that back as a choice, or tie it into the otherwise situation resistance aura.
currently the INQ has the plunder mana line to give some degree of mana back to the group (25% amount drained). this currently has both lacklustre scaling on the first rank and a long 60s cooldown. plus very variable mob availability.
it would be interesting if INQs got this capacity tied to a few more abilities.
such as their 'dispel magic' + 'purge' + 'purifying blow' spells, which could possibly restore mana to self/group as either static values or as a % of the spell's mana cost whenever you remove a magic effect
another approach would also be tying this sort effect into the INQ's self ward barrier line. have that also restore a portion of damage blocked as mana to group.
e.g. level 18 ward: restore 25% of 60 hp barrier (so 15 mana) to group when mob breaks the barrier (or per hit during). or something along those lines to mirror the current mana drain restore
re dire charm cd power
i'm still of the opinion that the INQ's emergency 'oh crap' cooldown should be a zero to low cast mana power with generous valued group HP barrier or group HP barrier over time like effect (without or without ward's low use slow rider).
also give it some spike in magic resist or something if we want that theme and an initial group magic dispel effect
e.g.
group cast, applies X hp (e.g. x4 str of ward) barrier for group for Y seconds (60s). applies dispel on inital cast.
or apply X hp barrier every Y seconds for Z duration, the equilviant of your latest WARD every 6 seconds for 24 seconds for x4 total applications per target). either applies dispel on initial cast or every 6s pulse for x4 dispels.
possibly throw on some self/group mana regen/restore too
