Invasion Suggestion
Several complaint threads have already been made with regards to Invasion and its difficulty (in both game-mode and mission requirements). Although I believe it is difficult too, I have a simple solution that may help with the situation.
The Plasma Fission Shots fired by the Vel'koz' should not split upon hitting a Champion.
One of the issues I have noticed is due to the small size of the safe zones and the heavy requirement for your team to stick together (to proc the revives), your team will get heavily punished if 1 player gets hit with a Plasma Fission. The slow and damage bounces to 2/3 people which drastically increases the odds of them being hit again and repeating the vicious cycle until everyone is low on health or dead.
Removing the split shot done by Plasma Fission reduces the penalty when your team has that 1 player who has the positioning capabilities of a Yasuo player recklessly spamming E whilst under the influence of a Quinn Q.
Any thoughts?
