I personally wouldn't do it. I'd sooner leave the match, wasted consumables or not.
Most of the games I've played had lag in some form, the ones that ran without problems were hosted by me or by people on Cable. As I know my connection is something akin to ADSL1 Dialup at the moment, I don't inflict it upon others and thus solo the game when I do get around to playing. In the country I live in, Cable is only available in select areas like cities and even then most areas don't have it (the last place I lived at didn't have it at any rate). Regional areas get the shaft and only have the option of ADSL2+, if there are enough ports on the exchange. In addition very few areas have Fibre since NBN is rolling out slower than a snail in some places. I'm about 4kms from my nearest exchange though, so my speeds are impacted by that on top of our copper wire infrastructure, on top of an open circuit line fault that my ISP is taking their sweet time to fix. I'm a bit salty about that, as it might seem. Anyway, I know my connection sucks, so I do try to avoid hosting when not playing solo, especially as my current download speed averages at 46kbs. Upload is a little better, but still terrible. 
On that same token, if the entire group agrees to kicking the host, then I say go for it. It'll be unfortunate for the host if they lose experience and gold (haven't been kicked from a game, so don't know if this happens), but hopefully they'll be able to regain it through another match.
