If there are "multiple scrappers" chances are that at least one of them can reach and/or -fly you anyway. I guess, flight would save you only in quite special circumstances and would hardly be worth the power choices and necessary slots.
If it has eyes, you can blind it, if it has blood, you can make it bleed, if it has a mouth, you can make it scream.
Keep SJ and get hover, its only 1 power, 3 slotted its okay at speed, and you can always SJ up then toggle hover to stay in the air.
leaping pool-combat jumping, superjump,acrobatics
stick 3jump heights in combat jumping and 3jump's in hurdle, best PvP movement power there is imo, esp coupled with superspeed.
Acrobatics is just so damn useful in PvP.
I am developing an Ice/Rad character for PvP.. I currently have SJ as I want Acrobatics but was also considering fly for those get out of Dodge quick moments. My PvP play style is RI followed by EF then run inside the cloud and pound to death with ice.. works pretty well but I keep being pwned by multiple scrappers.
Is it worth taking 2 travel powers so I can keep vertical range from scrappers or does the -fly element of many attacks make it a pointless option?
