If I may just make an ammendment to that, if you're only 'hacking' the replay to add emotes in then I'd consider that fair game, albeit a tad unnecessary.
However, if you're dropping in hacked dismemberments, thrust, etc, then no, definitely not.
No. Sorry, but you need to improve if you wanna get into ORMO. Try getting a decap or split. Arm dismemberments rarely look good. Try using more of the frames, make a madman or a combo with those frames. Show no limitaions in your replay making. Please re-apply another time with better replays.
