Reforge currently only rerolls the suffix and the stats of the item but not the main stat-this can make or break some equips especially for Rangers as they need all the attack stat from any source if they are Hera as you lose around 500 attack total at 6 stars if the accessory and vanity do not have the attack stat. At least allow it for prestige equips as some items like the war horn of the fury howl set comes with random stats.
If the idea is rejected, then consider the below instead:
Not really related but I feel the need to expand on the topic of the HP stat itself on equips and runes-currently the amount of the HP main stat on equips should be increased (for accessory and vanity) as they are arguably the worst stat to have on any equip because you would rather have other stats compared to it; as for the stat of the runes they are fine but the pink Giant rune or the percentage HP runes are terrible in the same sense that they give not enough compared to the other runes; you would rarely want to use them even on Faye and Aden because you can cripple them in PvE as you trade your defense for pittance amounts of HP reducing them to simply aura or skill slaves when you can use them for everything if you give them blue Guard runes of HP. The aura and skills based on HP can then be tweaked to be balanced after the change while making some of the items and giant runes usable.
Thank you for taking your time to read.
