well , i myself a player of PL since late 2011. stopped in 2012 and now i am back again.

AL is a very much plat focused ( or cash ) since best of the best items are found in lock crates. ( it's not cheap opening them comparing to spending plats in Pocket Legend)

After a while , it'gets boring in a way either one has overspent on plats or one does not even get any arcane or mythics.

PL is a different story , even though there is no cap for such a long time ( 2 years i assume) , things are not plat focused.

i have done PL , DL , AL and i still feel a sense of belonging in PL.

Hope this game would run for as long as it can.
