I know people like it for the big damage and the huge knockback but taking from my experience with the faust and the sealed sword, this line looks seems to be too slow for my liking and the knockback doesnt do much for you when you're up against multiple enemies as enemies behind them can come up and attack you while you're recovering but then it might just be that I haven't gotten used to them. I do like the speed and the fast 3 hit combo of the brandish line and I have half a mind to ignore the slow swords. I'm just wondering why the avenger is so popular, is the pro's much greater than the cons or what?
P.S. If you could mention how you use the avenger and what 4* elemental sword is the 'best', that would be great. :)
My alt is using Blizzbrand (Glacius) and the freeze plus average speed fits me better than the heavy swords. Plus I like to move fast while charging (slowed with DA/GF). Freeze is the best for soloing, and good in a party if the other players are smart enough not to thaw them early.
Combuster is good for a damage status, Voltedge is a medium between damage and crowd control. Up to personal preference.
I haven't used some of the heavy sword line though, but I guess, as with the "average swords" like Calibur and Brandish, last hit must hit all incoming enemies otherwise it's not worth doing over shield-cancel.
I guess Avenger is popular because of:
1. Big numbers
2. Massive knockback on swing 2 (I agree it's satisfying)
3. Flashy and effective charge attack
