I like the meteor ult,the dot very helpfull; the immortal ult needs 1 more stat like for exemple 20%critical hit damage or something ; grand protection needs a buff like make imunity to all control for 2 sec; herb ult needs a little improvement like 15%damage reduction or mitigation armor and aim shot ultimate should deal one arrow dealing 10% of enemys max hp or 3sec dot dealing Shadow damage, this is my feedback, i would personally give all classes one dot for 3seconds with element, this way all classes will be usefull.
