ok so the link is a proof on concept.
but i have an idea for how bungie can create more powerful exotics, however they come at the price of consuming super energy, (or ability energy).
1 such thing is the above link
but ideas i have had is
THESE ARE AN EXAMPLE/PROOF OF CONCEPT OF WHAT COULD COME FROM IT NOT WHAT I WANT TO BE INTRODUCES
an fusion rifle that holding reload, (for like 1sec), will over charge the fusion rifle (consuming super energy) allowing it to empty the magazine in 1 charge (but charge time is increased), quite similar to pocket infinity
or
a sword that holding a button, will consume melee energy (must be fully charged). will increase damage, blade size, swing speed and mobility of guardian wielding it for a period of time.
what about armor
titan, holding grenade will play an animation that grants, the guardian that cast it +50 res +50 mob and +50 rec, for 10 secs (continuing the trend increase, and going beyond caps (such as 150 res)
or
hunter, no super ability but you get an animal companion (void wolf, arc falcon, solar eagle), that attacks in different ways,
however in crucible will need to be summoned by consuming you dodge (with a effect that reduces dodge recharge rate (triples recharge rate) for the duration of the companions summon, so unlike PVE isn't permanent and comes at the cost of your super and dodge
