First of all, if they're gonna waste PRECIOUS gems then so be it! I'm keeping mine for the Hellrasier UP2 and etc.
RAP's already show off most of the time with their freaking anti-gravity blasters and 1 shot weapons...but just remember that they are little kids (90% of the time, sorry if I offended those people who actually worked their butts off to pay. If I did offend you, then you have my most sincere and humble apologies) that stole their mom's credit cards.
Anti-Gravity Blaster and Mini-guns are nothing if they suck at aiming. What I like to do is go side by side jumping every once in a while or if I'm close enough circle around them.
Lastly Tacos,
Don't hate, APRECIATE
