Both are unlocked at 0CP. We didn't want to give pioneers ambush camouflage (flamers, lol) but, at the same time, we didn't want to remove sprint from them either. That's because Tobis would always haunt us.
Hi I'm here to haunt you.
Pushing the sprint back to 1cp really neuters any alternative build orders besides grenspam that were possible with this commander. It's not practical anymore to use pioneers with sprint in the first few engagements of the map, which really opened up the doctrine to t2 rush strats for 222 or pgrens. 3x or 4x gren builds were already the meta before, locking sprint to 1cp leaves grens as still the only possible opening for good infantry play.
It's sad to see that this doctrine is becoming Elite Troops, but with sprint instead of stun grenades. It will play out with exactly the same build order. I would like to see the new commanders encourage the use of other build orders and strategies that weren't already possible in the live game.
