Lets see your roster.Hard to say about team rating. If you beat the collector, you likely have enough of a roster to do the monthly EQs.
There is an easy path in every quest without any nodes on it that you may be able to get through. Bosses will likely take units though given how low your guys are. Props for doing Uncollected so low, I had full team of 5/50 and may have even had a couple 5*s in the mix.
My strategy was to go as far as I could without spending then go back and explore chapter one.The T4cc shards alone from the daily crystal and chapter completions will be really useful to get your team to a point where it gets easier every month.There will almost always be one boss with killer nodes that will give you plenty of trouble until your roster gets deeper but synergies these days mean even a 3* can help a mediocre champ become good or a great champ becomes awesome.
I can do easy path with 4* 5/50, I have replaced my 5/50 domino with an 4/55 domino, so it’s a little easier, I sometimes have to use 1 or 2 revives on the boss but that also has to do with that I go in as a headless chicken (should work on that).It’s not really about team rating but more if they can handle the champ (and node), my team for example:CMM: indestructible and binary, she is like a cheat codeNF: Synergy with CMM and IMIW, gives a boost to team and very good on his ownIMIW: heal block, immunities when armored upDomino: for longer fightsCAPIW: utility champ massive sp2 with critOf course there is more to it, but the gist is that they all play their role.I have a bunch of 4 stars ranked up, like icemen, corvus, blade, human torch, gwenpool etc. for when I need a something specific.Like in boss rush, I used corvus 4/40 for medusa and capiw 5/50 max sig against emma frost was a joke, like 20 seconds and she was out.If you just save your 4 hour free crystals, you can pretty much explore uncollected eq with 4*, maybe a couple of extra revives with units.Just know which champ to use for what, that makes this a great game (and I should use my own advice more, too many times I stare at my screen “what just happened?”, Haha)
