I disagree with your opening statement, but agree on the mods. I don't think having limitless time should be rewarded with ever greater power in the game. There has to be a cap on this, and it should be somewhere that rewards people who raid and play more, but doesn't unbalance the game. Random Rolls entirely unbalance the game. However, I do think the guns should be more customizable through mods. I have no idea why there aren't 2-3 mod slots on a legendary gun that allow you to put things like Counterbalance, Reload Speed, Handling, Exploding Rounds etc. Put the best mods in the raid and trials.
