i stopped reading after a while because not only this addition to the game is unnecessary but your ideas arent exactly good.
BoP=used in 90% of speed builds, with your change it will be used in 100% of speed builds(builds that used wreath of lightning for the extra movement speed would just take bop now)
stricken=useless to broken depending on proc chance.
BoT= this is where i stopped reading, your change is a huge nerf to the gem since it would stack cc immunity to mobs in high GRs.
so i decided to make it a more construtive post, so i'll continue reading and commenting.
hoarder=no comment here, really.
Boyarski's=with that change some builds would have to rebuild, some tweaks here and there and thorns builds would be way too fucking OP.
enforcer=not bad actually but not sure pet docs need such a big buff.
esoteric=torn about this one, i dont see the point or i cant think of a use for it right now. hmm seems useless now that i think of it. so if something one-shots you for a trillion damage it would do 200b damage to a radius. speedfarming by dying? whats the purpose? lets say normal hits you take are around 400k, and thats a pretty generous number for supports, it would hit for what? 80k? what's the purpose again?
gem of ease=best idea i've read so far, but is it really needed?
gogok=getting to the point of wanting to stop readin again
iceblink=since it just stacks to 50 and no more, the damage increase wouldnt justify putting in a frost build, and it would just increase cluster in GRs since its used by supports. but this one is actually an interesting concept.
invigorating=you might need to rework the wording since the gem doesnt actually heal you but this gem needs all the help it can get so this one isnt bad.
mirinae=people would still completely ignore this gem
gizzard=you mention massive splash damage but at 500k LPS thats a "massive" 500k damage, doing absolutely nothing. no
moratorium=see at esoteric, damage done to you is so small compared to the damage you do so this is another pointless addition. lets say you have a 2m staggered damage. wow at 2m damage back at the mob! 2m could be good in leveling in lvl1 but then again you wouldnt get a 2m staggred dmg.
pain enhancer=mostly used in FB wd which uses fire, and the damage would be so low its pointless addition to the game.
red soul shard=no comment
simplicity=wow nice to see a broken thing after so many underwhelming damage bonuses. completely broken for gen monk if the proc chance is as high i think it is(50%+)
taeguk=keep the broken things coming man! firebats wd says hello and thank you very much, you just made it from no1 clearing class to no one else is gonna clear GRs while this gem exists.
wreath of lightning=with some teaks to numbers(buffs) this is actually a thing i want to see in-game.
zei's=i dont know about the numbers you have in your head about this one, it could be very good or pointless.
all in all i stick to my original thought about gems not needing another power. sorry if i sound rude or anything, i can clearly see you've put some thought and time on this one so i tried my best to justify why i say what i say.
