Without going into complete details with examples that one could find on their own, I have spent a couple hours focusing on the Caldari Sentinel and it's possible loadouts... Ranging from task specific loadouts, to playstyle/general combat variations.
At first glance, I saw great potential here... but then...

The issue that I found with this dropsuit, is that it has way to much PG, and not enough CPU.

With the 4 High slots and one Low slot:

Around 50% of loadouts - will be forced to give up the low for a CPU upgrade and still not have enough in a few variations...

...

The issue is that the 4 High slots on the Heavy have no PG heavy modules that can be used... Resulting in 50% to 70% PG useage on nearly every fitting.

There is no way to maximize this suit's slots, and it will nearly always result in the suit being a 3 high 1 low suit.
