Glory, Talisman, Dead Man's Plate, Spooky Ghosts and Warmog's all exist in ARAM
So why does Mark?
There are so many tanks that just have to waveclear until mid game that can count on Mark to engage with zero risk. Still yet they have all the tools in the title to make sure it's impossible to get away. God forbid they rely on their own abilities. I'm so fucking tired of this. Galio has been sitting between 65% and 70% win rate ever since Mark's release. I really can't understand how people complained about poke comps and they don't complain about this. At least poke comps are squishy to the point that they explode if you catch them. Engage/tank comps have been handed so many tools that you can do virtually nothing against them. There are still all those hyper-mobile champs sitting at sub 40% win rate that Mark didn't do a damn thing to help.
So what the fuck Riot? How can you still keep Mark around for 6 months when it's so blatantly broken? And I truly mean broken; not just unbalanced, but broken. It has no positive qualities whatsoever except for a placebo effect for people that think they couldn't already engage.
This really isn't the first time you've dumped something into ARAM without really considering all the different facets, but Mark is by far the worst offender. All of the other times at least fixed some problem, even if they did create others. Mark just makes already strong champions unnecessarily stronger.
Seriously, you cannot possible pretend free, zero risk engage is still a good idea when there are so many other options for engaging already.
