I’ve seen Lancers who take Peltasta as an off-shot class, and instead focus on DPS with the rest of their build. Specifically, Lancers, as their build is mostly about spears, but they might have a circle in Peltasta.
I’ve seen Clerics who abandon all support in their build starting R3. Either along the magic DPS paths involving Bokor, Sadhu, Druid, or Plague Doctor… or the physical DPS paths focused on Monks. A lot of Cleric options for DPS, really, and actually more DPS options than support options.
A kiting Archer is one who invests in mobility skills, but a lot of possible builds aren’t focused on such. Some builds for archer are even focused on single target burst. At that point, you don’t even want to try kiting, that would just get you killed.
While I’ve not actually played much with Support Mages (or even FS Mages), I do know that there are a few support builds with circle 1 linker (and many that take c1 linker that have a lot of dps going on). At this point, it just plays out like the other three situations above. You have a class which CAN link, but is focused on something else.
I really think people should try to, instead of just looking for someone who has a circle in something they want, find someone who is built to focus on a specific desired role. You request specifically someone built and designed to tank, to heal, to kite, or to link. If they have such focus in their build, and they claim an intent for such a purpose, then you can find reason to blaim them for not actually doing what they are there for.
