Using reagents profusely quickly get very costly.
A single dram costs 20¥, which may not seem like much. But, when you're regularly casting at Force 1 with a limit of 5 or 6, that's 100 to 120¥. That's the same as 10 rounds of APDS or EX-Explosive rounds, or 3 Assault Cannon rounds, or 1 frag or HE grenade.
Reagents can be highly effective for spells with single-target effects. For spells whose effects are based in some way, shape, or form on Force; not so much. Overbyte's suggestion of Edge + Reagents may win you a battle, but those kinds of tactics are likely to get you noticed somehow because that's a lot of astral signatures to clean up.
