LPhillips,
I guess I've never seen anyone employ this successfully on Battlefield and I've played a fair number of players there. Then again I tend to make gobs of reasonably fast L1/L2 units (Lt Calv, Eagles, Wizards, Giants) boosted with a RD or Pegasi and just swarm all over the map so I don't care much if they die in masses to Ghosts or Assassin heroes because they are so easily replaced.
we have a balance issue here. There's still no effective counter to this tactic, so in effect we have a penultimate strategy again, with no viable alternatives.
What you do mean by effective counter? You can use your own Ghost/Assassin stacks. Or use masses of cheap units that you can make faster than they can make Ghosts (trading 1 Ghost for a single 1 turn unit is a very bad deal obviously, trading 1 Ghost for a pair of 1 turn units is a bad deal and trading 1 Ghost for three 1 turn units is roughly equal). I still don't believe anyone can consistently maintain a 30 tile range with 1 Assassin stack against the fast moving cheap units I use.
Also the game is always going to have a penultimate strategy. ALWAYS. In the last Beta it was Demons. If you do something about Ambush (like remove it or seriously nerf it) then it will be back to Devil/Archon/Unicorn. In DLR the game revolved around heroes.
Right now it seems to me the game has 3 strategies you can pursue:
1) Gobs of stacks consisting of 1 or 2 turn units inflated with a bonus unit.
2) A few power stacks consisting of 3+ turn power units and bonus units.
3) An average number of stacks consisting of ambush units and other 1 turn units.
Strategy 2 beats 1. Strategy 3 beats 2. Strategy 1 beats 3.
