So a thread was opened on General Discussion regarding a player’s experience in transitioning to the 5* tier. I made a post there on how I did it and how I would advises others to do it - a lot of people did, which caused the thread to be moved to “Tips and Guides.” It occurred to me that probably the best thing to do would be to make it it’s own thread - here’s basically what I posted, edited to be more general. I invite others to post their own experiences in transitioning, and what advice they’d distill from their own experiences.
I started off with one champ 5* - Black Bolt. Black Bolt pairs very well with many, many characters, so I ran BB and a boosted 4* (I had a pretty full 4* roster at the time, and it’s only gotten better since.) I played this way for a few months until I maxed out Black Widow. BB and Widow pair together very well, so I champed her too. I then fully covered Dr. Strange, but since Stephen doesn’t play very well in PVP, I decided he wouldn’t be a great 3rd 5*, and stopped pulling Latest as soon as he was fully covered. I resumed pulling Latest after, as I wanted Thanos. Once I got Thanos, I then fully leveled all my 5s (in for a Penny, in for a Pound,) which at the time included OML and Strange. I champed Strange, as his build wasn’t great (4/5/4,) but have yet to champ OML since he’s very usable at 4/5/4. I’ll get around to it when I can spare the extra 20k Iso. I don’t have an extra cover for either OML or Strange. I have recently champed Black Panther, and am working on Hawkeye - I want Hawkeye for the diversity he’ll give to my roster. After I fully cover Hawkeye I’ll probably move to Classics until we see another top-tier 5 - I’d like to finish my older characters and get more levels for my current champs.
So when I had one champ 5*, my scaling went up appreciably - I stopped seeing 4* teams with any regularity and generally just saw a 5* with one 4* or two 5*. My PVE scaling went up too, but I expected that. When I champed Widow, I saw a lot less 5/4 teams and saw pretty much just 5s. I didn’t notice much difference if any in PVP when I got my 3rd 5. The PVE difference wasn’t huge, either.
As far as PVP climbing went, I could generally climb to around 900 (in S4) with a boosted 4* team before taking more than a few hits. Adding Bolt increased that to around 1050ish, depending on the time and other things. With Bolt/Widow I could make it to 1200 before shielding unless it was particularly “hot” out. Thanos/Black Panther has impacted this a little - I now take more hits since BB/BW isn’t as scary, but I still think I can do this (also, I now have Thanos/BP too, so I’ll switch to them when I get high in points.) I will definitely say it’s helped my HP income a lot - I spend a lot less on shields, and have to hop less. Also, I can get a much higher total though I’ve yet to score higher than T10 (well, I got T5 once in a fairly lazy bracket.)
The downside of this is you wipe a lot more with 5* teams - the match damage is so much higher that a bad cascade will destroy your team. You also consume a lot more health packs. I frequently climb to a good float point evening, then climb to shield the next morning. Sometimes I dig into my Tacos. If I don’t have much time to play, I will climb as far as I can get and shield.
In general, I would say you can play with 5s as long as you don’t level them past 390 or so - I noticed the PVP scaling kicking in at around 400. My advice would be to be careful with the 5s you champ until you have at least two good ones. You will want your first 5* to be one that plays well with others - Bolt, Thanos, even OML. I believe Hawkeye is too squishy (don’t have him yet,) and Strange definitely is (he rocks for PVE, though.) Widow can be devastating, but she’s too slow to be a good deterrent - she really needs a good accelerator (like Black Bolt.) I’m honestly not sure who else - maybe 5* Cap and IM? GG? PHX?
Anyway, your second 5* should play well with the first. After that, you can do what you want, but unfortunately this is the best way to deal with the scaling and not have an awful time of PVP.
