Ok here is the good and the bad of it. The changes are great and does bump the dps up, and casting every minute does save a bit of mana. I havent done crit checks yet to see if the bonus is working but my far from uber wizard is parsing around 5k dps using staff, CD, and rain clicky in between from full mana to oom. I tested this with familiar on, and with brilliance on from ssra shield and it equals out, more crits less damage or more damage less crits it just equals out. In doing this I discovered something interesting. The iceflame of eci buff which is kinda like a familiar in that it adds a bonus to your nukes overwrites familiars BUT it stacks with manaflare. Maybe the familiar could just be done away with and the iceflame spell be rewritten to work on fire nukes so get the bonus from manaflare too.
Something else I discovered. With iceflame/manaflare stacked using free mana rain clicky and stacking one other rain spell(ghelid rains) I can achieve identical dps with very very little mana cost. 5.1k dps from stacking rains with manaflare(of course there might be some resist issues on higher end mobs) but still an alternative to the I wanna big nuke right now idea of things. Over the same time period about 120 sec of being oom casting CD, a free rain in between, and two clicks of the new staff clicky I was able to achieve the same dps stacking those rains with mana flare and was left with 95% mana.
Just my thoughts hope it helps out in the further improvement of the class
