First of all, let me say this: This suggestion is for an OPTIONAL mode of the reticule. The default reticule would be how it is now, this would be a proposition for an ability to change it to this mode.
Basically it replicates the info at the bottom right, but near your center of attention, for when you need to pop abilities at crucial times, be you Hunter or Monster. In the above, Top/Bottom are at the ready, Left is recharging, and Right is used up. I used transparency in order to make the reticule less obtrusive.
Like with Monster abilities, when fully charged (abilities, not weapons), they could glimmer a bit when they are ready to be used.
Just a thought. There are many ways to represent ability state with minimal UI towards the central focus area; this is just one such suggestion.
