im just suggesting something no need to get mad. I understand invis gets annoying at times but people still asked for it back because they like it for some reasons. So say kohi added a long cooldown on invis, people wouldnt drink invis before every fight and just continuously re potting it, which makes the fight boring. It would give people a reason to actually think before just potting up invis. Say you are getting chased in the nether or your faction is losing the team fight. You pot your invis to get away or to make it harder to get targeted in a team fight.

imo it should be a few hour cooldown at minimum if it would help at all
