Other than that everything meantioned before didn't really alter the gameplay. Talentwise there aren't any big changes either. You now need to pick Ebenbolt as a talent, but the other options aren't too great anyway. You're probably going to use the pet again, but since water jet got pruned there isn't really any meaningful interaction (outside of openworld/trash fight/pvp) anyway. It also looks like we're going to run Glacial Spike. Some people like it some don't, but as it is right now it drastically simplifies gameplay (Holding brain freeze procs etc.). Also mastery is much better than before. When it comes to procs it feels slightly better since iirc they slightly nerfed the damage our procc'd spells do but increased the proc chance.
To summarize if you liked Legion frost you're probably going to enjoy BFA frost. The spec retained it's proccy nature, but it's slightly less bad since Ice Lance does way less damage than before and frostbolt crits don't reduce the cooldown on Icy Veins or increase the damage of Ice Lances anymore. And since Icy Veins lost a lot of its power it's less detrimental towards your overall DPS whether you get your procs during the opener or later on in the fight. ST and especially light cleave are Frost's strengths AoE is still its weakness, but manageable.
