With the new update where you can get trinkets for ASI/CTR/DMG i feel that the swiftstrike buckler has ran out of its uses

SS:
Normally people use SS buckler in conjuction with either full VOG or full Fallen set to gain MAX ASI for swords, and for the trinkets they would normally get resistances for damage incase their shield breaks. This is because SS buckler is a high risk high reward, granting a large ASI while having a Proto Shield. However now, just grab a ASI med trinket, and you already have MAX ASI for swords, and you can actually get a decent Tier 3 sword to compensate for your trinket loss

My suggestion is have SS buckler based on a "to hi" before break, e.g. 2 hits in Tier 3 before it breaks or 1 but after it breaks have an invuln that scales with the tier, e.g. 1 sec invuln in Tier2, 1.5 sec Invuln in Tier 3 which has a cooldown of maybe 5mins after the first invuln before its back

Vana:
Since they introduces slag guards as a permanent spawn instead of a spawn when walkers are dead, make it a top down view on all stages so you can see where the guards are or if the camera angle still stays the same, make it so theres a red line which indicates the direction of the charge so they cannot abuse the camera angle.
