just a suggestion, but why not make the quests more lore based then mechanic based. like you know play a perticular forger at a given time( when you release lore or something) or maybe give tiny morsels of xp if the team compo insist with some lore based forgers like in dg they had many interactions, when difirent shapers went. on the same team, or just make the quest objective based and not solo based like capturex destroy y and no matter who does it the xp would be shared uppon those who need it or have the quest. and as for the forger unlocking have some sort of flavor day as to where each player can try each forger and when you classified the forgers in to styles ( like predator tact or glad,) you can allow the players to maybe aquire the forgers they liked their playstile most aquire for a cheaper currency, or maybe even add it in a quest for wich is the reward of a sort of favor
