I think the game needs more give and take in order to truly balance the packages and AAs.
There should be a true reason you pick something with an advantage and a disadvantage.
For instance, if you have shielding, your base movement would be slower. This would allow you to get back into combat quicker, but you'd need to choose your engagements more wisely.
Another example would be mobility. If you have mobility equipped, you would start with less shield strength making you able to get around the map more quickly, but in more of a sneaky, rogue-like fashion to truly cater to that play style.
Tribes does this well, Shadowrun does this well with the different classes. A Troll in SR has more health than all other classes, but moves slower and is a much bigger target. An Elf in SR has the lowest health of all classes, but is the fastest and skinniest of all the classes.
If you're going to force players to make a choice with their AAs and Packages, it needs to be a conscious decision with a give and a take; an actual thought process being involved as to why you're picking certain abilities over others.
Take the Ninja Troll in Shadowrun. A typical Ninja Troll would have a Katana primary with a SMG secondary. Its slotted magic and tech would be Wired Reflexes, Teleport, and AMG's or Gust. A typical troll in SR was meant to be a Tank, one that could take a lot of damage and stay in a fight.
However, the Katana in the hands of a troll was only a 2 hit kill. So, players would SACRIFICE the ability to take lots of damage and use the trolls unique "harden" ability which cost mana to fill those slots with Wired Reflexes so it could have a faster base movement speed along with teleport which cost 3 mana slots with each use. Trolls also had the slowest mana regen of all 4 classes.
So, you sacrificed a LOT of what made the Troll class and Troll and in return, if you were sneaky enough, knew enough teleport lines, and made great flanking decisions, you had a class that was unique that you could play in a strong way, but at the cost of what would typically be the Trolls strengths.
