Hi Let s begin with the obvious: this is a click bait situation Let s recap Fusion dmg nerfed 5 % regen grenade with radiant on hit is not enough because you can t keep the radiant buff on healthy target i.e boss, mini boss, non dense area with red bars The 20 to 15 % nerf is noticeable and not worth the trade off 2.5 % with 5 % on hit The lack of restoration for a solar class unless you give up torches but this mainly due to the lack of fragment 4 is just not enough. I mean in order to get resto ×2 you need to eat a grenade use phoenix dive then have such a short time to proc a kill that is really quite the setup sure you can extends for 2 sec with a fragment but then you need all the 4 fragment dedicated to make the loop resto ×2 going This is basically dmg and no survability at all or survability and no damage at all whereas titan and hunter don t have this issue. Solar Warlock subclass NEED more fragments I mean look at hunter with YAS ... this ... this is a looping dmg setup like warlock can only dream of
