As a player, I would want to have explained how giant spiders with no intelligence would be reliable allies? Do Spriggans have some type of ability to gain this understanding?
I got that covered

5 feet in 6 seconds seems reasonable, if a little slow. As someone who actually burns thick spiderwebs when they are encountered around my house (only outside and only when it is safe to do so), I can tell you that the web just evaporates and does not carry enough activation energy to light anything else on fire.
Since these webs are thicker, and more like thin rope or string, you could argue that the fire could continue. Even if it managed to light something else on fire, the fire would be small as there would still not be much energy transferred. That being said, you can make it behave any way you want to, but every once in a while, you need to indulge the pyros in the group without too much consequence.
Well maybe not instantly set the roof on fire from the webbing, but now you have a torch on the roof.Gotcha. So it's reasonable to think that if they threw a torch on the roof, it would burn a 5' patch of webs and maybe make the rood smoke a bit but it wouldn't instantly set the house on fire.
