Yeah, I know they limited how much it chews. But they didn't limit how much it pulls, resulting in what others have reported in that it spits the ships out "whole" through its rear. Further, the cone of angle for the "chew" is actually wider than that of the pull....
Re-studying the files, though, it looks like it'll take more than a simple text change to fix it. First, the convert buff is applied once. This means new ships that enter the area affected will be pulled, but not chewed, even if it didn't hit its max, yet.
Second, aside from one time shots (instantAction), there is no way for it to track cumulative targets affected. IE, if on first application there were only 5 targets, but on another application there's another 5 targets, it'll still see it as 5 targets, not 10 total.
Maw will require code changes to fix.
