not really since the low lvl players dont use that many troops and they almost if not completly rely on free or cheap units.
and we are talking so small numbers per adventure that loostspot prices will only be affected with say 50-100 gc´s in the beginning untill the prices of them dropp again.
however when the lootspot rises a little in price everything else will fall down to a cheaper state. and to me its okey to see a momentarly rise in the price of a lootspot if it fixes the prices on the rest of the market.
If the fee on creating troops are to great then some will stop making them. thats not the idea, the idea is to make the fee so small that it dont really matter for ppl.
