it seems to me that shoota boys are now more effective than sluggas, basically shoota boys get an extra two shots per turn at st4 (albeit at bs2) for a loss in one (usually) st3 attack. Say over the course of two turns you charge your mob of orks towards the enemy. The shoota boys will get to shot twice then charge (for example) so they would get 4 st4 shots from the shootas, plus 3 st4 attacks from the charge. Sluggas on the other hand only get 2 st4 shots from the pistols, then 4 st4 attacks. In effect, one attack from a slugga boy (usually hitting on a 4+) equates to 2 st4 shoota shots (hitting on 5s) in this case.

Once you take into account the range on the shootas and the fact they can still move and fire(meaning even more shots put out over the course of the game) it seems to me that this is much more effective than an extra one attack that half of the time is going to be at base strength anyways.

If anyone has any thought on this matter please feel free to elaborate, thanks in advance.

Cheers,
