Collective ranking strategy is going to be very different from player to player.
Players with fewer 7★ champions will probably focus more on ranking up 6★ or even 5★ champions depending on their available resources.
A few important points to consider:
1. 7★ champions are the most valuable long term investment
In the end, they replace any lower tier Captain version of the same champion.
On top of that, 7★ champions can also gain an extra 200 points through Sig levels, unlike lower star versions.
2. Some champions still do not have a 7★ version In those cases, the highest Captain version is currently the 6★.
That means those champions are especially valuable to rank up to Rank 4, since they can reach 830 points.
So even if you don’t have many 7★ champions yet, it may still be very smart to invest resources into 6★ champions that currently do NOT have a 7★ version available.
How can you check if a champion has a 7★ version?
I’m attaching screenshots as examples:
Guillotine currently exists only as a 6★ Captain
Magik already shows that a 7★ version exists


I would also really appreciate it if Kabam could share which upcoming 7★ champions we should expect to see this year.
We already know Thor Ragnarok is one of them… but who else?
Is there any list of current 6★ champions expected to receive a 7★ version in the future?
Feel free to share your own strategy as well.
Because on one hand, everyone wants to maximize Collective rank progression but on the other hand, we also need to spend our resources wisely and strategically.
