Why is this such a wild idea, of all the things in the game that could be deemed unhealthy; Kleese Rift Gates having this change would be extremely minor on that list. Blocking people is a two-way street with Kleese as it is now, I really don’t see usefull applications for using it to fully block a door since your own team needs to use every path aswell other than for a last ditch block on a enemy you’re chasing. Even putting Rift gates arround the sides of minion waves can be detrimental since your own allied thralls can block your team, making the occasional giant wall your own team can’t pass. The Rift gates themselves are super vulnerable to AoE and there isn’t a way to heal them AFAIK and those with both ranged attack and AoE can keep the Rifts in check. And you can already pass through your own allied minions and no one thinks that’s unnatural or unhealthy and we would probably be pissed if it wasn’t the case.
And on incursion, other chracters are walls in of themselves like Alani or a Miko x Montana where nearly any other character would be pushed back and denied a kill if their prey were behind one of those characters. At least with Rift gates you can throw and O.Mike grenade and they disappear unlike a Montana x Miko who would not even care about most things in the game barring 2 or more AoE ultimates. If this change were put in, in general i’d imagine people would be happy with it rather than groaning about it being imbalanced.
Collision detection in general and the huge characters people have to work with has always been a problem for many players. Of course you can say deal with it (as I do) but with how small and vulnerable Rift Gates are I don’t see much of a loss to the state of balance if you could phase through them. And with this change it would make playing Kleese that much more interesting and dynamic and allow him to put the gates up more aggressively without the draw back of denying a path to allies or constricting an already narrow area like the bunkers on Overgrowth or the side buidings of paradise. And the more aggressive Kleese is the more vulnerable he is which makes this change work out in my mind, and again adding just a smidge more depth to the character.
