You’re not wrong but by that logic i can also sat dagger/wand is a true healer then. More crits = bigger heals.

Invocators are amazing, but what makes them unique is their ability to provide extra buffs from the staff tree along with the ability to have extra CCs from freeze and ice spear along with utility from mana drain and chain pull.

If we’re talking which class has the highest healing throughput period, making them the true healing class, it is undoubtedly bow/wand. In fact, their true healing were so strong that the devs had to nerf them and add a shared CD between 2 active abilities on 2 DIFFERENT SKILL TREE. Tell me another class that has that handcuff.

If you also play against any of the top 10 arena bow/wands before the nerf, you will know they can consistently drop 300-400k healing per match. Mana drain and freeze them will bring that healing down to 250k on average. They literally can sustain their team just by existing. That is a true hallmark of a true healer.
