U1 R1 R2 R3 R4 R5 R6 U2 (R:rogue U:unnatached(main) T:transformed rogue)
and this is what a pair of turtles can do:
1st turtle hits R1 tranforming rogue R1,R2,R3 and damaging U1
2nd turtle hits R4 tranforming rogue R4,R5,R6 and damaging T3 and T2
..so going with rogues will be a bad choice against some turtles
Regardless of its movement or speed (the turtle is the slowest unit of OF and AF) Inno has given turtle a higher 'initiative' parameter value than other theoretically faster units like the rogue, BF, CRAB and plasma giving turtles more turn priority than it should based on its speed or movement parameter value
Turtle is a really good unit against CRABs and artillery ...and rogues, ofc
but has no chance against stealth and flying abilities and other faster units (hover tank, eel, drone, recon raider, subcruiser...)
