If you're playing Rieekian and have to choose between Precision Strike, Superior Positions, and Fighter Ambush you could really let your opponent harvest a pile of tokens off of you.
Except: didn't the clarification on Jamming Field wording make it clear that card effects are optional unless stated, so Rieekan is an optional effect that you could choose not to use, to avoid the detrimental effect of being farmed?
I think part of the issue with that is, when does Rieekan activate?
