I personally think the new raid system will cause more players to leave... the game is already hemorrhaging players... getting harder and harder to find replacements... the players with the needed factions relic'ed will not appreciate carrying the others for the same rewards so they will leave to go to guilds that have similar rosters so its more fair for them and get better rewards in the process... which will cause more players to leave the guilds losing the more equipped players... I foresee this causing more issues than helping
IF something like this was implemented before the current state of decay in swgoh it may have worked great... at this point I think its a sharp stick in the eye to the player base
