Make old feast rewards somehow available again

[Commander_Justitia]

only the cheats have it.

There was cheating even in solo-queue in season 1 and 2. Me and my pvp fc ran into a fair few speed hackers

How can 1 guy out of 100 be "only the cheats have it"? Your wording is off and people here sometimes don't know it better (because it is some time ago now).
And are you sure you mean feast and not frontline? Because playing with your PvP fc sounds a lot like playing frontline with them.

Season 1 and 2 had probably the least issues with boosters/cheater/wintrader, competition was high, and lots of good players played it. The mode was too new for something like that.

why though?? it makes doing PvP not worth doing at all then?

idk dude, if there is a mode you don't like, you don't have to play it only because there are rewards that are exclusive. You can just go on with your life and ignore pvp. If you "hate" PvP in this game, why bother about the rewards?
Oh, so you actually like the rewards from it? But you don't want to work for them? Well OP is asking for a way, that makes them obtainable in a "grindy" way, so you would be spending even more time in PvP after all? It is pretty contradicting don't you think?..
And making formerly exclusive items available on mogstation instead of in the game again, would send a very bad signal. Legacy players don't want to see their exclusive mounts on mogstation either I guess.
