Thanks for answer mate.
I don't think all the +6300 crit rating legacyes are trash, if you use
https://lotro-wiki.com/index.php/Rat...entage_formula you can see that for a raid mob lvl 108 you must have
CR = ((1190/3) * Enemy's Level * %) / (1 - %) so if you wanna have a 30% in yellow traits (spendin point in red line to Deft Strikes) you shoud have around 18300 crit rating
so if you must have a mitigation/morale build like in Mumakils fight, the legacies, expecially crti-chain one, can help in reaching the goal of 18300 cr.
If you go DPS, in raid against lvl 108 mob to have the full 32,5% critical chance, you must go with 20600 cr (ok you will be buffed by a cpt etc, but you know, more is better). To give in your build some space to finesse/mitigation/morale i think +6300 legacies are not so bad. Not both, but the crit chain one i think is very nice for raid.
If i think to my bag legacies, the MUST HAVE are
positional damage
crti multiplier
reveal weakness
trick duration
addle damage debuff
So i have 2 spots and chain CR i think is fine. (DidE we know is useless against raid bosses)
