Here is my situation:
I currently have 232,681 iso, 765 hp, 8LTs, and 9cp. I’m totally F2P, Shield Rank 93, day 785. I primarily play PVE to progression in SCL7 or 8, and occasionally shoot for t50 placement to get the HP for roster slots. I play PVP to 575, though increasingly as I a accrue 4* champs I’ve been able to hit 900 without shielding by playing at off hours - I don’t pay any attention at all to placement in PVP, but playing the way I do tends to leave me around t100. I’m commander in a casual public alliance, so we don’t get loads of resources from each other.
I have every 5* with some covers (no champs), save Green Goblin who is on the vine waiting on HP, and JJ, who I missed in the Alias store.
I have every 4* on roster, 15 of them champion, many at 12 covers. I have a lvl 131 Chavez (3/2/5), one on the vine, a lvl 131 MEHulk (3/3/5), one on the vine, and a lvl 172 Flaptain (5/3/1), one on the vine.
I have every 3* on roster save Colossus, all but 23 at champion. I have a lvl 40 Dar3Devil, lvl 76 D3adpool, and lvl 40 Sh3-Hulk at 13 covers with one each on the vine. Blad3 and B3ast are at 13, no vine covers.
I have a functional 2* farm, still working on my 4/18/2 Bagman but everybody else has been turning over nicely for some time. I have a lvl 15 Thor ready to re-champ with 3 on the vine. Wolverine, Moonstone, and Ares are all a few covers from champion, still at lvl 15, with many covers on the vine as well.
I keep a lvl 30 max-cover 1* Sp1der-Man for DDQ.
My tentative plan has been to save up enough iso to try and save Chavez - expires in 7 days, or Hulk - expires in 9 days. Flaptain expires in 4 days, and I don’t like my chances of getting 4 covers on him with the token “hoard” i’ve saved up so I’ll probably just sell that cover off. I’ve been saving LTs as I get them waiting for JJ, who is now in tokens. Chavez would be my first choice - and is my 4* bonus hero, but obviously RNG gets the final say there. I also have loads of characters at 10-12 covers with some levels on them that might turn out to be options (lvl 209 Hulkbuster, lvl 209 Sandman, etc) as well.
The amount of iso I need to go from 131 to 255 on a single 4* is as close to the same amount it would take to champ 3 3s as makes no difference, so if i swing for that fence and miss, I figure I can champ my 3s 1 at a time for easy LTs. I don’t really think it makes sense to throw iso at Thor at the moment, it’s easy enough to come up with that kind of iso through a little targeted play in a day or two. I guess as I write down this plan, I still feel like saving iso until Chavez is about to expire and pulling my LTs is the move, but I’m curious what y’all would do: try and save either of those 4 covers or just take the low-hanging LTs offered by the 3*s?
