I want to see that kind of bracket - top 10 of mine always have 200+ X-force, usually have at least one 270, and most will have two or more 270’s.
Totally agree with OP. I have 25 127’s as I’ve gone with even leveling for PVE (15 of these could go to 166, about 5 ‘optimally’ covered, two of those actually any good. Zero iso currently to do this with). This keeps me out of the range of 2*'s as someone mentioned. Step one, accomplished!
Step 2 I thought was to move to a few 166’s. But I hit a solid 166 wall just after 500 points in PVP. Say I get four decent 166’s - each match will likely take down one enough to not be able to go forward without a health pack, of which you get five. So I can go 4 + 5 matches: 9 matches, except every time I win one past 600 I assume I’ll continue to lose two - the ones I lose now aren’t to 166’s, they are to 270’s.
I don’t think the OP idea of flooding with 3*'s will work unless you are flooded with ISO to actually level your characters.
I’ve already talked myself into just jumping right into 4*, why not? 3*'s won’t “shield” you, but a good 4* roster will make 3*'s skip me a bit more, just like a good 3* transition roster makes 2*'s skip me a bit more. I’ve saved up for two X-force covers, and bumped him to 200+. Next is 4hor covers, and bumping her. May as well save all my ISO and just hit up the 4*'s, why bother getting the 3*'s higher when they won’t “win” anything but more 3*'s?
Which makes the game more P2W than ever. The only way to actually get into that 4* transition is have TONS of HP, so you can buy the covers - like folks mention, must have the 4*'s to win the 4*'s. And HP is such a scarcity that you pretty much have to either have already had all the 3*'s to win 4* covers when shielding worked, or you have to now pay to get your 4*'s (many claim they haven’t, but so many max 4hors all over makes me wonder).
The P2W is so obvious I’m sure it’s intentional - it’s the devs letting you know right away the only way to “win” is to get into 4* land by paying it up. I guess at least you have to earn the 4* covers initially since you can’t outright buy them right away (or find them since many don’t show up on daily rewards for a year). If covers become more available (or purchasable without a first one owned) and HP remains incredibly low, I’ll feel vindicated in this assertion.
