I like MN Magneto too. But mine is only 3/2/5, probably aiming for 3/5/5. I really like the low countdown on the blue.
Also, I just got first in the Hood LR. I really, really like Patch. My team was 124 Patch, 85 Original Widow, 75 Hood. Never had to use a health pack. I only got attacked maybe 6 times, and the attackers lost half of those. Patch's healing, especially backed up by Widow, is crazy, and keeps him in a match indefinitely, and dual AP stealing from Widow and Hood means the enemy almost never gets off a power. Typically I'd trade matches with their Hood (if he had a high level blue) or their Original Widow while saving up AP, then cover the board in strike tiles and take down two characters in a single turn. Level 70 buffed Ragnarok was no problem at all.
I suspect that people were really hesitant to attack me because, even though he's likely to hurt himself too, nobody wants to risk Patch getting 9 green and then triggering a cascade, and they can't really go for Patch first because Widow and Hood will suck them dry.
This is actually my first LR finish better than top 25. Hood is now 4/5/3 and I'm a little tempted to just throw down HP on his yellow since it becomes awesome at level 5.
Also, it seems like Original Widow is now one of the scariest characters on defense. Boosts were emphasizing her fragility, but now it's very hard to take her down before she gets going, and she slows down your blue, purple, and black skills and can potentially ruin your day if she gets enough purple. The closest I came to losing a match or character in that LR was against a fairly tame OBW + Modern Storm with a low-level Hood team where Widow got an early purple cascade and proceeded to keep me drained, keep herself healed, and keep Storm in green, red, and black. But as long as I kept Patch in front I was basically okay, since he's healing 300+ hp per turn, and even though everyone got down under half eventually I was able to get enough purple of my own to break out.
