SUGGESTED fix, and yes that is the point of link, to mitigate your tanks damage onto the backline so the backline who is safe due to the tank doing their job can easily be healed and the tank will not be 1 shot by the absurd damage ratios currently present in the game.
Contrary to popular belief, linker is indeed a support class, meant to make mobbing and dungeoning easier through it’s ability to increase damage output and decrease damage taken by using physical link and my proposed change above does just that, because by double applying defense through my formula damage is essentially removed from the equation.
Example: Tank gets hit for 1200 damage normally, his defense lowers that damage to 1000, linker physical links this tank to his party, tank who would have taken 1000 damage (after defenses) now takes 200 damage (spread equally across a 5 player team), those party members then receive 200 damage a piece without their defenses factored in, instead we now factor those defenses in (and all things equal for all 4 other people) would take 180 damage a piece, so now you have an effective damage taken of 920 (200+180+180+180+180), thus removing 80 damage from the effective damage taken.
As it currently functions each player linked would take 1000 damage, the ability is broken and does not divide damage, it is simply a joint penalty for your own team, it’s broken, clearly because that could not have been it’s intended purpose.
And all their attributes are pretty useless too.
