The Netherweave bandages have been reduced to 600 hp in 6 seconds some time ago and the others (except Classic tailoring ones) are level locked.
That said the Mageweave bandages (Classic tailoring 210 req though) still heal for 800 hp over 8 seconds and are the best avaiable to f2p to my knowledge. Always nice to have buuuut...
...all that said, the grind isn't really worth it even for soloing. Maybe for DK/DH which are unable to heal in combat without hitting but the best use I can see is if the last boss from docks is kicking your butt as one of those classes, allowing you to heal from your hiding spot.
In the end level tailoring if you wanna or stick with Netherweave bandages (way easier to get), I wouldn't say it's necessary but if you feel like having this option to heal a little, please yourself
