My problem isn't about premades, in fact I have defended premades regularly in the past on those very forums against people that wanted to see them removed. My post history is here to show for it, and I took a lot of flak for it.
My problem is about the lack of care SE put into FLs, where the problem has been actually pretty serious for years and yet they're reluctant to invest any resources into addressing it, and how this allows for abuses. This all boils down to abuses, and while it was other things before, today it's DRK-AoE spamm abusers which is not only totally braindead, but also leaves no room for anything else if executed on the field.
