Best way to check if attack speed is off/on cooldown?

[closetcheater 0]

Working on a script to manage attack speeds for end-game PvM bots with heaps of gear switching and DPS checks. Current workaround involves checking the weapon item ID, manually determining the tick count for each item, and using onGameTick() to count ticks after each hit.

This works okay but if it goes of sync for one reason or another it breaks.. wondering if there's a more efficient way to check if an attack is on cooldown. Have I missed a class or method in the API that handles this ? Any tips or alternative approaches would be really appreciated. Thanks
