With the revelation that you will able to do weaponskills back to back I don't expect skillchains to be to potent at all.
Repeated use of the same actions makes the actions weaken over the course of the battle (also: there is a tp guage in addition so "back to back" may not be accurate in the first place), there isn't any reason to lower normal skillchain dmg given that this mechanism is already in place.
I had heard that skillchains were not nearly as popular end-game or that their usage decreased a lot over the years, but I wouldn't know because I quit a while ago and never reached max level.
People quit using SC in endgame because everyone firing one off as soon as they hit 100% is more dmg efficient than waiting and "wasting" tp. If they want to fix this all they have to do is make WS use a specific amount of tp (w/ a considerably larger tp cap) instead of all of it at once and decrease/eliminate the SC dmg resist rates.
