Fnatic Buds is one of the best reapers in the pro scene right now, and here's why:

Buds proved to be fnatic's star dps player at gamescon, outshining one of the best McCree's in the world and teammate IDDQD, and it's all because of his unique play style.

The general assumption is that reaper is used best as a high-damage flanker, good at taking out the squishies and supports while ripping into the tanks. While this is true, an organised team can deal with a reaper who plays this flanking role very effectively. Yes, reaper has very good survivability, but if focused down, can be taken out easily due to the lack of movement capabilities and teammates to help him out.

Buds plays the reaper in a way in which I've never really seen before at pro level. He almost acts as a second mccree, patiently sticking behind Rein's shield, laying in damage to the front line. This team-centered approach may seem like a waste of reapers damage, but if used well, it can drop the opposing Rein shield very quickly and open up the play effectively for his team.

A second advantage of playing this way is that it also increases reaper's already good survivability. If he gets jumped on by say, an enemy Winston, he can lay the same amount of damage he could when flanking, but this time he has the support of this teammates that will not only help him win the fight but also keep him in the fight longer. This also helps gets rid of staggered spawns, as reaper will mostly likely go down with his teammates rather than having to hop back to regroup.

Buds himself has stated that in his eyes, a good reaper needs a team with good communication and good comp in order to work well and that's why he'll rarely play him in solo queue. Top tank players from teams such as Envy and C9 have also praised Buds for his positioning, stating that he's one of the only reapers they can't get close to at all.

I hope that Buds' recent form can open the eyes of reaper players to other stats they can employ, other than just that 'sneaky sneaky flanker role' the may feel restricted to.
