D.A.R.C.I. and Legend of Acrius should be moved to the special slot; In PvE, They do not provide the necessary punch needed to consider them powerful, in PvP, having them be available only to heavy boxes provides an inconsistent experience, with them holding no define advantage over other weapons that are similar.

The Farm: Put a shooting range there that has Cardboard Cuttouts similar to what policemen use in their shooting ranges, the location could be in the little cellar that is unreachable under the hangar, and it features changeable health / damage modifiers, for example Raid Enemy health + a modifier or 2 that increases damage, or player health in Crucible that can have the resilience be tinkered with
Black Armory Forge: Decrease the recommended power to 580
Competitive matchmaking is separate from Quickplay; Quickplay has its own hidden rank that increases based on how well you do in matches (not Your Win / Loss Ratio, make it how well you do, like your k/d (kills/Deaths) (not KDA, or Kill/Death/Assists)),
Comp: Either do a separate Rank similar to the previously mentioned Quickplay, or completely re-work it to start at a set number (1000?) that raises and lowers based on if you win / lose the match;
Party Size is also determined (if you are only one player, get matched up with a team that has at least only one solo player (example; if you are on a team that is 3 people in a fireteam and you as a solo, the other team must be the same)).
The thing with darci getting moved to the special slot is that it's strong aim assist, while great in pve would be horrific to deal with regularly in pvp, and with acrius if it was moved to special they would have to rebalance it's damage so it wouldn't one hit supers in pvp. So I understand that it would be great for them to be moved to special but knowing bungie they'd would really have to tweak a couple things to balance them in crucible for fairness, sadly alot of the things I would love to see changed around in pve wouldn't be right for crucible.
