I am an old school Hansel and just recently came back to game. I have LL and HL full of SOS. I have HF now with 2 level 1 ice trees. On HL I have changes 2 SOS for lv 2 Vols. Question is: does getting another lv1 Ice Tree on HF give more benefit and plunder than exchanging a lv3 SOS for a lv2 Vol?
Yes, it's a lot better IMO. I bought as many HF lands and built Vols, them when I got bored focused back on HL. I'm now gonna buy all HL then move back to HF until the land is around 500B, then focus on T3 L3.
I would venture to say yes the ice tree would give more plunder.. Not sure the exact value.. I would just build whatever is cheapest
