Ion cannon is already put into it's own profile and it's a been a thing since ebf2.
And is outdated, AND doesnt have any calc so is merely "eye calc"
Damn i dont think exists a britain in EPBF, and even if it was i dont think there was any britain show in that feat
Ebf5 would be thrown into a blender with how much is going on, 1. The speed of the expanding event horizon, 2. Everything in sight getting sucked in with no spaghettifaction or destruction, unless the everything on the planet including early game fodder tier grunts and the planet itself upscale to having blackhole resistance which is really unlikely to be acceptable.
EPBF black holes are alredy deemed as valid tho
Oh also giving those effects would be
1. To much work
2. Destroy low gamma computers
You know that those FEATS actually would scale to the character rigth???? than EPBF 1-4 dont scale to any those feats and EBPF5 would actually scale AND most of these are not calced
That is my point i bringed these feats that actually gives rating instead of being merelly suport calcs, and those alredy have a pseudo linear progression
Tsunami Tier 8
Nuke Tier 7
Absolute Zero Tier 7 to 6
Ion canon Tier 6
Supernova Tier 6 or 4 depending on how they do the calc
Also i never said it was necesary, i just a way to make the profiles better, as they work to give different feats even if they dont brinn that much hax
Oh also Deku Final act profile basically has those "problems" amped to a trillon
1.Literally only a tier diference
2. Like only 7 More haxs
3. And not necesary
4. Not different enough
A new profiles isnt just to give new abilities after a key, it also can work to make the profile more clean (wich EPBF need a cleanup)
