Basically a guideline for a new player on how to set up a Reclaimer build with 4 pieces without the ninjabag. You should be able to get these parts quick by grinding a bit.
High Electronics and Skillpower means a good amount of healing from the bag, and if your bag goes down, use First aid on an ally to get the cooldown away quicker! And off course, use first aid all the time on your allies to keep them alive!
You don't really have to use the weapons i suggested here, whatever you have access to will be fine. However, you do want the talents i suggested, since that will help you a long way in getting your skillpower and in general your helpfulness way up! I just like the LWM4 for its accuracy, and the M700 Carbon because its basically a good sniper rifle. However, you can switch it out with any kind of weapon really, just look for those talents! And remember, you can reroll 1 of them! Talented is the most important one.
In general, stay back, and keep healing. But since you do have a decent amount of Firearms, you will also do a bit of damage in a firefight! But I based this build of you staying within you own circle of healing, since your Stamina is low. But you can switch the Firearms to Stamina for more survivability if you want that instead.
