Merc: Ele shots reloads and supports

I would like to submit that the Electrical shot on Mercs put all other shots to shame. The fact that it has 5 shots really doesn't bode well for the use of any other shots in the lineup. So I would like to submit that we need the number of shots each elemental shot should receive should increase per level until skill level 5 so that fire and ice shots have 5 total shots by the time we are receiving VI level skill gems.

In addition, switching shots when they have 0 ammo should reload a shot. 100% of the time. We should not have to be pressing these buttons twice when switching to any shot on the list of skills that currently has 0 ammo currently. It makes no sense. It's just unnecessary extra clicking.

Auto reload as a skill gem is in the wrong place, it should either be a passive at the beginning of the class's lineup of passives or it should be part of the first points used on the secondary class choices in the passives tree for this class. Having it as a gem just makes it an insult to injury.

And finally, there are several frost gems that are doing absolutely nothing with the frost abilities. None of the ice abilities at level 5 or later put any frozen ground nor are they affected by the 50% frozen bonus from the support gem.
