Inspire Abylityes - for a why different tiers needed?

[Krinharth]

Please explain, what gaves t6 tier, that can not satisfy T1?
tier of mobs, I suppose? (i.e. t6 mobs drops shards only with t6 abylity used, am I right?)
or no matter what tier use?

[Cilok]

The tier of the ability works on all mobs up to that tier (so tier 1 mobs can drop shards under any tier ability, t3 only drop when a t3-t6 ability is used, and t6 mobs only drop shards when a t6 ability is used).

Thank you. so I suggest right.
