The last thing you want is for DE to get all bright eyed and give loki a "long overdue revisit" only to ruin the frame.
Let's look at each frame's rework from front to back
Atlas: Didn't do much
Banshee: Generally not touched, but her 4th aug has been killed
Chroma: Dying in a hole full of fire and smoke and burning and torture and anguish where he lives to suffer and burn and choke and scream and cry forever and ever till the end of time
Ember: Not as bad as chroma, but terribly executed
Excalibur: Started great and has only become worse
Frost: Not as good as excal but still decent, but the nerf to cold damage really hurt him
Hydroid: That's a negatory sir. Nerf to loot killed him and his rework really didn't do much
Limbo: Started fantastic, overpowered even and has slowly become worse
Mag: Net sum zero at start, becoming slowly worse and worse
Mesa: First rework sucked. Second rework was terrific, but remains one of the most hated frames in the game
Mirage: Nothing good really
Nekros: Net sum zero, desecrate is easier but nerfed. shadows is buffed but static number
Nezha: Overall a buff with a terribly stupid nerf in there
Oberon: Pretty good
Rhino: Good overall
Saryn: Cite Chroma
Trinity: Cite any trinity meme
Vauban: First one was meh, second one was decent
Volt: Good and better
Wukong: Some good, some VERRRY BAD, overall bad
So if tally the positive reworks to negative, we got 14 bad ones and 9 good ones. That's an overall negative, and even the good ones weren't really the best. The only ones with really good results was Limbo, Volt and Oberon. The rest were either some good and some bad or kinda good. The rest were 100% bad or useless.
Point: If you like your frame, shut up and use it. If you think it can be better, suggest a NEW frame that has what you want.
