Personally I have also tried the build where I have full -Skill Costs passives from Shaman trees and the like, it does not really help that much XD. I still inhale MP pots like oxygen. Infact, I inhale it faster than HP pots especially in wars.
I do like the mechanic that MP is thoroughly useful now, if you dont have it, youre dead, so you need to weigh your options everytime.
But it is starting to be costly.
I had like 1k Mega MP pots, I spam there like a bish when Im going dungeons. this was 2 days ago? Then now I only have half left >_> LOL
VH Greater MP potions, (20%) are now streaming 600k gold+ per piece. Hwawh.
Food Mp Pots (Christmas Soup, Witch Elixir, etc) are around 1mil+ per or more.
Crazy k. Its Crazy~

For CH farmers though, I recommend asking a sage or templar for help outside Payaso NPC to heal your MP. Im sure ya'll have alts. Just regen yourself and youre good to go. LOL
