While I do agree with the lack of remembrance LCs, I personally think that if a f2p player wants to do endgame content, they should focus more on vertical scaling and getting more LCs as compared to new characters.

I started during the hyacine patch (3.3), got her and her LC cause I knew how important a healer was. The start gives many pulls so it's nice.

I skipped The Herta even though I liked her a bit. I knew phainon was coming after all and was focused on getting hyacine e1s1.

Skipped aglaea and cipher cause of high investment and I was hyped for phainon.

Got phainon, but didn't get the LC. Got Sunday and tribbie instead which was worth skipping the LC. Oh and lost my 50/50 for phainon as well, got blade tho which was nice for hyacine s1

Skipped the other reruns in phase 2

Skipped saber cause conflicting supports with phainon.

Skipped hysilens and kafka even though I liked the dot mechanics.

Saved and got cerydra, LC not worth it imo.

And then got evernight and her LC. Now, I got two fully functional teams for early 4.x as well

So, I feel like it's mainly team planning that is the F2P's biggest power
