Not even kidding.
Get-Off-Me move? Check; horizontally, it's better to get characters away from him. Vertically, you need to be precise.
High damaging move? Does 24% damage sound low to you?
As for a combo starter, this may sound silly and it is quite tricky, but Link has getup options that Izaw had touched upon in the Art of Link video, such as F-Air, but considering the patches, is F-Air able to combo into anything? Yes. Like his Z-Air hit 2, Link can successfully get a Dash Grab on any opponent (except Jigglypuff due to her weight) by just using his F-Air at very low damage. This sets up for his D-Throw combos and into a plethora of attacks, although it's only reliable at lower damages, it's all you really need if you hit the opponent.
I've done this on players online, offline, in-tournament offline, haven't missed a single combo like that, unless the opponent shields or is in a better position, although the latter rarely happens. But Link's F-Air has other boons such as the range, early killing ability and the ability to hit twice.
Link's F-Air isn't anything to laugh at; it's one of his deadliest moves in the game and definitely one of the best aerials in the game for any character. Sure, it's a F14 attack, but its boons defeat the purpose of the slow startup. If you land one hit, your opponent's going to be thrown off.
Definitely by no means the best, but it's one OF the best in the game by far.
