I love the Thunderlord, but as an exotic heavy, it would be nice for it to get some more love since we have to sacrifice using an exotic primary or secondary for it.
It has an extremely high DPS/looks great/ sounds amazing, but it's exotic ability merely increases its fire rate which is immediately lost if you let go of the trigger. The hidden firefly(legendary tier) perk is there as well of course but it would be great if it was more evident.
Causing every target to explode might be a bit Op but could be balanced to where the blast radius is reduced. Then again it IS a heavy exotic, which should make it worth using an exotic slot for.
There are other exotics that are in more dire need of attention, but i still wanted to bring it up.
