Basing might not take too long for me.....but painting and detailing and customizing sure does
So...if I had to start from scratch to put my Utes together, it would take me weeks to finish. I don't always have a lot of time to devote to the hobby...especially since I have other hobbies!!!
Basing isn't too difficult for me now....but it used to be. The best advice I can give here is TAKE WHAT THE BASE GIVES YOU and don't try to make it something it isn't. If a base is naturally fast or strong....enhance that. If the base tends to loop, fine, don't work too hard to straighten it out....use that loop for a blitzer or back who can attack the perimeter of the "D." This method speeds up basing a team....and in the end, probably makes it a better team
