I am not to keen on Force Scream because it just doesnt seem... Well, I mean force scream is not a power you hear to much about and it seems kinda childish whiney... To me it just doesnt have a fitting feeling... I feel that destruction would be much better. The concept of Scream is nice, I just have a feeling that it may not be... pretty. But I am not 100% against it either.
Force stasis I am against fully because you can already be slowed by having low DP which lightning will do in time... And you already have Force Speed which can close the gaps. It doesn't add to the games overall fun factor if you get my drift when 2 other powers can be used to gain distance, especially speed. Not to mention Pull can also stall them.
