I cant be arsed to address every quote, so i will just address some of the stuff that hasn't been addressed, and some that has.
1) A ROB who is proficient with his laser and gyro and who is familiar with the stage terrain and consequent angles, will be able to snipe you from most places on the stage during Wings of Icarus. I can't count the number of times a Pit has thought they were safe by using it under the lip of a ledge, only to get my laser angled down the stage and hit them. Forget going under the stage.
2) ROB should not be gimped in this matchup. Once is possibly acceptable. Fire arrows all you want. That just means we can f-air them while offstage and conserve our fuel. Firing rate is essentially irrelevant in this situation, bc the distance between Pit and ROB should negate the delay in aerial usage after the up+B cancel. If you bend the arrows below him, and maybe sometimes above him, it gets a bit frustrating, but smart airdodges, aerial mix-ups, and Up+B use will eventually get us back to the stage with a safe amount of fuel left.
3) Walking powershield negates most of your anti-approach arrows. Mix in F-airs with that, jabs (yes, jabs cancel the arrows), and f-tilts... we should be able to cross FD after taking 3-5 hits. With ROB's survivability (lack of true momentum cancelling aside) this isn't too bad.
4) Pit dies earlier than ROB, even without gimps.
5) Pit's reflector is useless unless the rob telegraphs it. The shield- SH and angle the laser down over the top of the shield. Glidetoss a gyro down, approach that way, and you guys eat a D-smash, as the fact that we get turned around during the bounce-off is negated by the fact the smash hits on both sides. Not to mention, if we space the distance properly, we will probably have pushed behind you. Angel ring: full hop, laser down.
6) Once we get close enough, walking F-tilt while at medium percents hits faster and is repeatable in the brief hitstun+startup animation of your arrows. Seriously, if we get in your face at mid percents, (try to) use your arrows. We want that.
7) Your best offensive strat is to get below us in an area between -45 degrees on either side of him (this includes directly below him).
My opinion:
55-45 (ROBS favor) if the ROB is decent on the offensive
55-45/60-40 (Pits favor) if the ROB is sub-par, or inept at being offensive
60-40 (ROBs Favor) if the ROB is comfortable on the offensive
These "percentages" are also heavily influenced by stage as well.
Ive probably missed a few things, but ive been drinking.
