Need Gear Help Please

[Krutch Undefined]

I'm currently a pure mf blizz sorc. I'm almost at 400% mf and want to change up my gear so I can do more damage. My current gear is as follows:

Shako
Tal Ammy
Tal Amour
Tal Belt
Occy
Crappy Faschuta on Switch
Perfect Spirit Ward on Switch
34% FCR Spirit
43 mf War Travs
Magefists

Charms:
1 Cold Skills
Torch 14-16
Some single res charms and Small res all

My resists are (in hell):
18 fire
75 cold
75 lightning
13 poison

I'm just looking to do more damage without sacrificing to much mf as 300-400 mf is decent, I would like to stay around that range.

I just need some guidance as to what I should buy next and after that etc. I'm thinking either a COH and arach (but that would be almost all my runes and I have to get arach if I get COH because tal belt sucks alone). But that puts me down almost 150 mf. I was also thinking of a blizz ormus but then I have no resists. Death fathom is a little to expensive atm as well. So let me know what you think I should do.

Thanks.

I think you should stay with your current setup.

With that gear, there is no way a blizz sorc can't do enough dmg. You'd want better for PvP, of course... but for pure blizz mf, it's plenty. What's the point of sacrificing other stuff for killing meph in 5 seconds instead of 8?

I honestly see no point in boosting the damage lol. Do you plan on mfing bigger games? like joining baal games just to do meph? If so, then I guess boosting the damage is a decent idea.

I really don't understand why people will get hr value items just to mf solo :P

What should I invest in then if I don't need to change up my gear? I know an anni charm but other than that I really don't have any use for much else except for some small fire res charms because I don't need anymore mf.

I also don't understand why I'm only doing around 5k dmg when other mfing sorces have around 7.5k dmg without BO. There must be another mf gear setup for them to be able to do that kind of dmg and still have mf.

They use war gear and load up mf scs. Very silly imo. 5k with cold mastery is overkill for mfing purposes.
