All new spells are cool i think, my only worry is that they are gonna derp again with green fire and either leave the old casting spell animations or they wont make the effort to make them as cool as the fire ones (like instead keeping the black particles of the spell animation they'll make it all green, which will be like throwing poison around). On live i went at some point and disabled green fire out of curiosity to see the legion implemented fire animation and i was like so...disapointed. Green fire looks so outdated compared to using normal fire in legion.
meh the new look for some spells are ok but its still missing something
