Buy heavy exotic from kiosk. Use heavy telemetry. Burn 6 motes. Dismantle for two shards some weapon parts and motes.
Rinse and repeat.
Costs approximately 2500 glimmer a shard that way.
Bungie logic *let's take out exotic shards,add exotic drop booster than nerf it to the floor, than make able to reforge anything but guess what? [spoiler]you need shards[/spoiler]
Before you Guardians spend 13 strange coins for [b]ONE [/b]shard. Please read my previous post :
(Cuz a Strange Coin is a terrible thing to waste)
Why waste special coins ?
All you need to make a shard yourself is 2500 glimmer and 6 Motes.
1 Buy Rocket Lauchers from kiosk
2 Pop a Heavy Telementry
3 Use 6 Motes
4 Dismantle Laucher and get 2 shards
5 Repeat
You also get 2-3 Motes back from dismantling, some glimmer and weapon parts.
