This is my take on Reclaimer PvE build. This is the build where you can do little more damage as full electronics stacked healer build. The Destructive in Free slot of Primary weapon and Enemy Armor Damage rolled in Vest and Gloves which results in 53% Enemy Armor Damage. Damage To Elites in mask and Knees provides you extra damage which you lack. And with 10K electronics pulse you can do real Damage.
I'm Using Skill-Haste mods not Skill-power mods because you want your box faster as possible after it runs out and while using Skill-power mods your healing rate only increases by 1.5k and that would not make significant difference . Using Skill-Haste you can get your skills faster as you are getting 34% skill haste when outside the box and 49% with additional 15% you get from station and skill-haste cap is 50%.Yeah you can use 2 skill-power mods and 3 skill-haste but its the same thing as additional 6k skill-power don't make any significant difference in station healing rate thats why i am going for 2 Damage to Elites Electronics mods for additional damage which results to 36% damage to elites. And i'm using Support Station range Performance mods not healing rate mods that is because without healing speed mods your healing rate is 28K Hp/s which is enough for all Endgame content and with Station range mods you are giving your teammates more room to run around.
You can use Skill-power mods and healing rate performance mods and get above 32k HP/s healing rate from your station but you are getting your box and pulse little late and box range is also smaller which is ok for resistance but not in other Endgame activities.
M700 Carbon is in secondary because as a healer you are mostly staying in the back as Legendary mobs are a lot tanky so leave them to the teammates and focus on buffing them via pulse as there is Coolheaded in Free you can get pulse quicker then the pulse duration so no gaps between the pulse, Trust me teammates will thank you.
Coolheaded in Free and not Determined as to proc Determined you have to kill the enemy which is little difficult as there are damage dealers in team and Coolheaded can proc with headshot only.
The sidearm there is Blue one as talent requirement is lower in that. You can use Yellow 204 Gear-score sidearm too. This makes you easier to farm your ult faster because of Coolheaded, You can swap between pistol or M700 depending upon the distance to proc coolheaded. And there is 3 seconds cooldown to coolheaded to proc, so that won't make any difference on using m700 or pistol for coolheaded.
You can change your Signature skill to Tactical link while playing Resistance and use Pistol in higher wave to farm your ult, you can proc your ults 2 times a wave doing that .
Since as a Reclaimer your job is to buff and heal your teammates but when you are playing as 4 man team enemies are scaled to 4 persons and have higher health but with this build you can help your teammates a little but more by doing damage too.
1 piece of advice :- Always pop the box while inside the box before it runs out to not only get overheal but also lower cooldown for next box couz if you pop box when outside you only get 34% skill-haste but if poped inside the box you get 49% shill-haste which makes your next box faster!
In conclusion , with this build you get 36% Damage to elites and 53% Enemy Armor Damage which helps a lot . :)
