And you cant use PHATBOYZ against anything other than swarms really, most core L2 kbots can make mincemeat of them (Sumo, Cans, i think morties have a longer range too, as do dominators)
Pyros are good raiders, and with a well used scuttle, you can create a gaping hole in an enemy defensive line, allowing you to swar... i mean plod through with sumos, cans etc..

Edit: just checked, PHATBOY costs 2251 metal, sumo 2020 metal, (but alot more energy) similar range, similar speed, but the sumo is a whole lot tougher - not saying this is wrong though, just quoting some stats
