Right now you can run ultimate for tier 5 loot at A or even A+ at a delta of 0 or even +10-20 if you are smart with the customise option for the modifiers.
So how is forcing a -30 delta at all times supposed to be making it easier?

well, it will make it easier because with the new system you will not have to play as long as right now. Once you hit 470, with the new system they talked about in the recent twab, you can just leave and uninstall the game. Because, with the new system, "power" grinding to 550 is bascially useless. But seriously, the only times where I had to play solo ops at like maybe -40 or so, was a few a runs around the 399 to 400 power level mark, but that also was back when the new system just came out and it's way easier now. I honestly believe, those players who complain about having to run -60 for a +1 are just adding -20 modifiers to get an A+ score, but ignore stuff like locked loadout, no starting ammo, pressure cooker, ... Otherwise I have no explanation for why...
