Though I agree with most of the standings in your rank system, I strongly disagree with your slights against Baron/Kulev. He is an absolute beast with a ton of potential as most of his abilities can be self, friendly, or enemy cast. His damage potential is quite astounding for a support character as well.
Maybe I am too invested in the character. I see you mentioned baseline stats. I'm assuming that means you didn't dabble too much into the rune/power possibilities? Even without, but quite more powerful with one or two new runes. I'm routinely able to 2v1 or 3v1 depending on the build I'm running and the comp of the attackers.
I will say, my true love still lies with Maeve though. She's a powerhouse once you power up her 'Schadenfreude.' With that being said, there are quite a few games where I end up switching to Kulev from Maeve for the clutch wins. From what I've seen, a lot, of the few people who play support players, aren't that great. A lot of horrible positioning and, even worse, diving!
Hope to see you all in game soon!!
