The main thing with the weapon changes is understanding how the timing works especially during combat. For crossbows you'll notice a brief charge-up animation before power shot launches, so position yourself early and watch enemy movements while it loads. The spear mobility stuff takes practice but once you get the rhythm down you can chain storm spear into a quick retreat keeping perfect spacing.

Weapon swapping is super precise - there's about a 0.5 second window after using a skill where you can smoothly transition between sets without animation lock. Good positioning near terrain features lets you maximize this since you can buffer the swap command while moving. Most people miss that you can actually pre-load a skill from your alternate set while mid-animation of your current attack which creates some really tight combos.

The crafting system ties directly into combat timing too. Your socket setup determines skill activation speed so pay attention to link order when setting up weapon swap combos. Class synergies matter a ton here - warriors get an innate 15% faster weapon swap speed with two-handed weapons while mercenaries can animation cancel certain crossbow reloads if you time the weapon toggle perfectly. Just remember that specific skills lock you into their full animation regardless of swap speed so plan your rotations carefully especially during boss mechanics.

Quick note that flails have this interesting sweet spot mechanic where landing hits within a specific range actually reduces your next swing timer. Takes some practice but mastering that spacing dance really opens up the skill ceiling for hybrid builds. The system rewards precise positioning and timing way more than just stacking raw damage numbers.
