General Notes
>Since the lack of healing power and water makes it hard to keep your health above 90 percent espically against single target dps builds I’ve instead opted to use rune of air on most builds to deal lightning strike damage every 20 seconds. Personally it made it much easier for me to keep up the pressure and even if u are on the defensive u can still chip away a bit of health till u get your cooldowns in order
> I’ve ditched diamond skin altogether unless u fight against comp that is majority condi damage because again keeping that hp above 90 against competent players or players of equal skill level to yourself is a no go. the stone heart allows gives u more sustain. when u need it at the same time. the sigil of cleansing and purging in combination with cleansing fire work surprisingly well.
>ether renewal is a decent other option to deal with conditions. I’ve used ether renewal on marauder fresh air staff cause i prefer aftershock to deal with projectile damage if i need it in a moments notice. if u stay away far enough condition builds aside from the condi chronophantasma shatter are not gonna be a that hard to deal with. ofcourse aftershock is not mandatory and u could Always use arcane brilliance/glyph of elemental harmony as a heal skill and cleansing fire. this was more a personal choice and in no way mandatory.
>glyp of elemental harmony is the most balanced heal skill imo in terms of casting time and heals given, if u are playing any other build then a healer/bruiser role.
would love to hear your opinons
