Right now Ash doesn ' t contribute at all . He kinda does , even if he makes things invincible , they are CCed , he rekts their shit after . Just as an exemple , last day i had a rly hard sortie 3 defence bow only , and this Ash in the party just got us thru it with ease , he even asked me to stop slowing mobs with my nova so he could kill faster . And btw i dont play much ash , as i said im just scared that they will use this kind of mark system on other frames , and the repercusions that it would bring to the game , i refer as a nerf just because you could be shooting at things instead of marking things while taking damage , so there is no much point using the skill at all , or not using the skill just because the mobs will be dead by the time you land it . But also can be considered a nerf since instead of killing a bunch of enemies with no effort , you will kill much less with it , with alot more work .
