Don't skill Inferno against meele opponents. It's a slow and vulnerable animation I only use it against classes like sharpshooter or other sorcs. Also in general you do not want to knock your opponents down too much if you do not have identity meter. Sorc combo requires opponents to be standing and knocking down an opponent with inferno gives them opportunity to roll in and catch you this is why Inferno is bad in 1v1. It's a great peeling tool in 3v3 and can do good damage if it hits multiple targets and also be used to re-catch/re-knock opponents who used roll. But in 1v1 it's a high risk low reward skill and doesn't even have paralysis/hard stiffness immunity. ("stagger" immunity)
You can use the tripod "wide-angle" on Ice Shower against opponents with low knock-up/push skills like gunslinger. If you play against classes like striker or wardancer can you hide in your 2 lightning vortex if everything else is on cooldown. Since you also have 2 lightning vortex you can try to raw-catch with them more often.
This build allows for a superior skill rotation. Don't spam them all at once, rotate them so you have little to no windows to get attacked.
You run 2 hard cc. Squall and Ice shower. Squall can be used agressively and true combos into awakening. Ice shower should be used defensively. Over-heat on lightning Vortex causes the duration to shorten by 1 second (from 3 to 2) but if you are fast enough it still true-combos into esoteric reaction and punishing strike.
In general sorc is played around safety. You are squishy and can't run away without identity. Don't get yourself in bad situations by fear-casting (throwing spells at opponents even though they are out of range), spamming spells in retaliation or getting baited too much. In general your gameplan revolves around not getting catched. Your opener skill will very often be frost calling. Frost calling true combos into squall (if you are close enough) and lightning vortex.
