Well to get it faster you need to load more bots targeted at your account lists.  At RoDv2's current build it only uses the same cdkey and only switches
if it picks up a invalid/bad/in-use cdkey. 
Also at it's current build, there is no delay when connecting bots, so usually if you try to connect more than 7-8+ bots in a row in one exe you'll
get ipd for too fast connecting.  So what people have done is just load multiple exe's launching 4 bots within each exe. 
And there is no limit for cdkey's.  You can have infinity bots on one cdkey. 
Namebotting is always risky business and its always a good chance you'll get banned.  But one of these days I'll hop back on this project and
add more features and options to make that less of  a risk.
