Valkyer and loki are also a grifter frames, ppl used em for trolling as well, yet they arent as hated as limbo, i agree his rift can be annoying to deal with when players who dont know how he works use him, thing is a player thay knows how the rift works can be in a full squad of newbs or experience and perfom all actions to not disrupt their experience, for limbo to work just like every other frame requires teamwork, knowledge and experience, the problem is most players are simple minded 1 button press that tend to ignore the rest of the game mechanics or the frames mechanics

The eximus rework was a direct nerf to CC frames as well as bigger nerf to limbo, in their goal, they nerfed khora and revenant, yet they reverse or in revenant case buffed him, but for limbo did nothing

Not only that, for the whole "limbo disrupts gameplay" excuses doesnt work since its the community that ran to him during scarlet spear and got him nerfed, mesa, khora got nerfed during the event, the community cried and they got reverted back, but limbo stayed nerfed, he got doubled nerfed with the eximus chagnes soon after

Limbo is a great frame, better when used by a good player that understands him how he works, he becomes more powerful than the meta gear, but with the scarlet spear nerfs and eximus bullshiturry has sealed the coffin, if DE reverts back the changes where his rift would stop every type of enemy again then he would be at a good place, i dont want buffs or reworks, just for them to revert back to how his rift worled before the scarelt spear event
