yes, tyrr glad got duelist spirit, and that's awesome, but tyrr doombr. got passive what add pvp damage, and the new skill bloody soul (dunno if it's passive or active) but increase pvp damage too. i don't know if with the new 34 awakening classes, it goes back the old specific skills of 3rd class and lose common skill within current tyrr? i mean (for example) tyrr duelist will got war cry, disarm, final secret again? and tyrr doombringer will got final secret too, etc?)
duelist spirit is 3rd skill so it will be deleted after glory or echo. so no reason to do gladi just for that.
i dont think nothing when i will saw them ingame and will get to play with them then i will discuss till than its just froth till chapter 3 lindvior ncsoft can change them thousand times.
i think this reference from terragamers will answer your questions but dont take it for granted that it will be this way.. http://wiki.terragamers.net/index.php?title=chapter_3_tyrr_warrior
duelist spirit is 2nd class skill ... he will be deleted? nevermind, i'm idiot replaced him ... but i wanna sonic rage forever!
if you are up to date and read patch notes you will see the echo updates totally changed the game mechanic, they are like small fix packages. i'm not sure we will get them before the next big update but classes will have a total remake, if any class can keep some skill still just keep them and use the advantage.
