I know it is early days for weaver tree but having presets (that either cost memory amber every time you switch equivalent to the cost of respeccing all the nodes required or just like 3 total presets) would be very nice for target farming things. For example when getting low on gold or low on memory amber or wanting more runes you can switch to a weaver tree preset that helps me target farm these till I do not need it anymore.
It could also be used for farming other things like weaver will presets or specifically unique farming presets. Although its use cases might be niche, I find myself switching my tree around fairly often right now since my needs vary frequently from wanting more exalted, to wanting to juice my 0 LPs with Nemesis to needing more Gold (because paying 400k for a stash tab is getting expensive lol).
Being able to freely switch between like 3 presets (even if it does require a memory amber cost) would be very beneficial.
