if your going to play bloody roar make sure its bloody roar 3, PF got scrubified evade is way to easy to do with no risk, unlike 3 where the timing was much harder required 2 buttons to do and left you open if you mistimed, as you already said sidestepping in PF is utter BS it moves you to far to quick and lastly and probably most damaging to PF the air recover, hitting recover in PF will free you from any air combo instantly with no timing required effectively destroying air cancel and air juggle system in place.
other changes in Primal Fury
they totaly revamped the hyper beast. in 3 once you had max beast you could enter hyper mode making you very powerfully and very fast with high regen and any cancel point, the down side is it lasted 12 seconds and when it ran out you lost the ability to transform for the rest of the match. in PF you can go into hyper mode at any time but it will take a large chunk of your health away, the more beast you have the less health you lose when it runs out you revert to human as normal and can rebuild beast, also they toned down hyper mode and gave each char a special passive ability (jenny for instance gets vampiric regen on attacks, bakuryu gains damage through block) noobs will attempt to spam hyper beast in PF but it gets them killed quickly.
you can now air cancel with QCFuF commands, for example if your by a wall with shina QCB+P, QCFuF+P would cancel the recovery of the qcb+P and go straight into the qcf+P attack.
all the stages, music, models, costumes, story (lol), graphics engine etc. have been changed id say its more of a stand alone spin off game than a remake.
as for a command list just use google, its not hard to find. and for the hidden beast drives
Shina - 360 degree + punch on a crouching opponent then B,P,B,K,K. the timing is tricky start the second part soon as shina launches the opponent
Buzusima - QCB+throw (QCF+throw in BR3) then B,P,K,K,B,B. again the timing is tricky
Cronos - 360 degree + B (only works in hyper beast)
Long - b,f+K,f+B,d+P
Shenlong - after you have gone through the combo circle in any direction d,d,d+B (when you get the red electricity do the d,d,d+B)
