Of course, sometimes those "dirty tricks" can get you into trouble. I've seen using units to block people's movement get so annoying that house rules have been introduced to help prevent it :) Make sure you've judged your opponents well :)
So, in other words, people can't figure out a counter, and so cry foul? Admittedly, I would only
use those tactics in a non-zell environment, and only if I was playing someone who has already
said they want me to go after them with the kid-gloves off. Or if the opponent has been being
a jerk...
That said, the counter to Encirclement is not moving within the movement range of that many units.
Of course, at that point, their presence is STILL influencing the battlefield, which is the whole point.
That is, of course, all part of tactics. Like knowing the options for where your opponent can go, and
plotting to intercept them at the best point they could move to...or do you see people making house
rules against that, too? Or hit and fade attacks(those are also frustrating, after all! SOmeone runs
in, shoots at a high TMM, then the next turn runs away and hides, then rinse and repeat every turn)
Sorry...but if an experienced player(more then a year of active play) cannot deal with tactics effectively,
then they do not have my sympathy, and I will switch from coddling them to seeing if they can learn
by having their back to the wall. But, then again, my group, as much as we play to have fun, have a
very competitive streak to how we play. we will call people out on jerk tactics, but, frankly, we all have
our jerk tactics that we can and will use if someone makes it clear that "Oh! it's going to be like that, huh?"
