For last 2 seasons i have pretty much exclusively played es fireballer/meteor sorc on ladder. Here is a screenshot of my stat sheet right now:

my equipment is:
Fireball ormus +19-5 faceted (5/4 facet will replace lol)
3/25/-5/23 eschuta's
6 aura 13 flickering flame tiara
10 aura pheonix (sadge)
3 fire skills 75% osn reduce ammy
fcr ring and mf/res ring
arach
magefist
mf/res 53 mana 5 max mana boot
es/tstorm/ca cta on switch
After all this playtime on this one char, i have as much experience as anyone with sunder fire sorc. Currently i have -50 fire res as shown in screenshot, so with sunder charm any monster anywhere will have max 45% fire res. Ervery single end game guide for fire sorc has infinty for merc. I disagree with this 100%. Even p8 cows/baal/chaos, i prefer insight to infinity. It does more damage yes, but i can comfortable kill diablo with 2 meterors and a few fireballs solo with infifnty, or 3 and some fireballs wit insight and never carry potions. Even with pheonix, the meditation boost to me lends to a smoother experience than running through enough mana to have to potion in addition to pheonix.
I would like for others to weigh in on this and other aspects of fire sorcs, such as obsession versus eschuta's/ pheonix, mf-focused builds, and anything else you might want to add
