He’s pretty bad. As someone else pointed out to me (and you also identify), he’s actually worse now than when he released and was considered a pretty mediocre option.
Healing is worse (both long-term and short-term healing)
Lamp is worse (shorter duration, less health, longer cooldown)
His primary is… slightly better, but the major buff to it was reverted, so overall neutral TBH
And his ultimate is worse, with a considerably greater charge cost (and slightly longer duration)
Really, the only thing untouched are his Exo Boots (which are… kinda clunky) and his Burst, which is decent but arguably not that special.
