I may not always agree with Pengu’s point of view on some topics, but in this case, Niclas makes a lot of sense.
Buck seems to be too versatile for Ubisoft’s liking.
Buck and Sledge are frequently compared to each other since they fill in a similar role – both R6 operators are masters of creating openings in the destructible surfaces.
When it comes to soft environmental destruction and establishing vertical pressure, Buck is second to none (not even to Sledge).
However, Buck has limited capacity in regards to dealing with defensive utility. In fact, his only tool for dealing with the utility are frag grenades.
Sledge, on the other hand, is superior to Buck in dealing with gadgets, such as Evil Eyes, Deployable shields, and Armored panels. That has always been the case.
It seems though, that Ubisoft would like to create an even further distinction in the specialty of both operators.
