I don't know if it was intentional or not, but since the last patch, only at-wills build the soul sparks stacks, compared to previously when encounters could build them. In addition to this, critical hits no longer gives soulsparks, even though they should according to the feat tooltip.
This causes a HUGE reduction in dps since 1, soulspark stacks directly increase dmg, and 2, the cooldown reduction mechanic can be used much less often.
Most people I know who play warlocks build sparks quickly by popping an AoE which fills almost half the meter. Now that is no longer possible and we have to either choose to waste time building stacks with weaker at-wills , or pop our bigger encounter powers with a significantly lower damage boost.
Please fix this. Warlocks are already behind damage wise and this hurts the class a lot.
