Shao, for the love of god... get the idea of "Nascent Flash's primary purpose / design philosophy is to support your co-tank" out of your head. Nascent Flash is a two-fold purpose skill with both effects being equally viable, given the right situation.
It is also not fair to shoe-horn Nascent Flash that easily into comparison to all other target-utility just because you can target someone with it.
- Intervention can be used along with Sheltron as long as you have 100 gauge, Raw Int + Nascent can't.
- The Blackest Night only works for a single target at a time, but has the shortest cooldown + a resource refund to compensate.
- Heart of Stone also only works for a single target at a time, but instead of a shorter cooldown it allows you to transfer Brutal Shell to a target, as negligible as it may be.
In comparison to those, Nascent Flash sets itself apart for having two purposes at the same time, which more often than not don't need to happen at the same time to make the skill viable.
- Mitigation & minor recovery for a target
- Large recovery for self
In practice, Nascent Flash is more often than not used to recover HP, particularly if you are the current tank of a target and situationally it gets double efficiency from double-busters. The keyword is situationally.
The problem for many WARs out there isn't that they don't care about applying Nascent Flash / Glint to a target if an attack is about to hit them for massive damage or to deal with fluff damage. It is when the situation of getting a benefit of Nascent Glint, Nascent Flash's secondary effect is simply not possible but using Nascent Flash would be more beneficial for self than using Raw Intuition, that is where Nascent Flash has clunkiness regarding input and should be improved upon.
The solution to this issue - allow Nascent Flash to be cast without a target similar to Dragon Sight from DRG without applying Nascent Glint to anyone
The solution is NOT - nerfing self-benefits of Nascent Flash / buffing Raw Intuition just to make Raw Intuition 100% the go-to skill to use. (putting this here preemptively before anyone comes up with this idea)
What this effectively would change is allowing WARs who are MT / current tank (i.e. where 90% of the time there is no benefit to apply to anyone else) to use Nascent Flash without requiring a macro for swift use or without having to learn hot-swapping targets to use it. This would only make the input easier, the actual use would be identical as before.
