Burst Fire maxed. Now what?

You don't need more than 1 ice splitter for a while if you newties. Sniping is best for newties at 8x unless you got enough HP or HB to take bottom. Even then you only need to freeze the first one and that's accomplished with level 1. You gotta have some good gear to effectively do bottom though or it just takes a while to kill. But even so, having an archmage/bishop at top is fastest.
