Yes. That's what I basically do against even Regen opponents. However for immortal build , I have to wait many rounds before the hit frequency can kill them. 8 rounds at most for me. Sometimes 12.
Also unless I revamp my build for pure damage with the risk of low survival and higher chance of defeating them per round. I remember someone used high hit frequency with procs , Crits and Deadly strikes to an insane level to beat immortal build in just 1 found but they were vulnerable to many other builds.
Already orb can hit 10 times a second. Cosmic orb can hit 10 hits with a chance of extra 10 from the cosmic orb strands so total 30 hits. Storm hits 4 times a second or so. Have many procs and you have a better chance, especially with higher DMG.
I mainly win because of that high hitting frequency despite them having really high damage reduction and sometimes against Regen opponents in one round. In fact my build was heavily nerfed because that hit frequency was OP and the damage. Also it forced the arena meta to become even tankier than it was before.
High hitting skill with high damage along with attack speed and low cooldown . Also good proc chance. Also a chance to survive recently with these things as a second option if you don't like waiting for draws.
Cerebral Vortex already has a hit frequency of 12 hits a second if 3 torrents hit and CV was the name of the arena meta for quite a long time because of such hits and hard to escape. Combined with other things like cosmic orb, my orb ,skulldraga (3 hits a second or so) , storm and win.
In fact even when arena was first introduced, it was the high damage and hit frequency that won and sometimes builds with high tanking or a mix of both.
