Yes Ruby players are needed, but when the game deliberately goes about pushing out free players, with random hits, loss of troops, wc and messages not working, and dragons that don't leave the city, even when they're lit up....it's just not working that well anymore.
One cannot win any battle lvl 1 in a wild without 1k troops....and Anthros cannot be won without longbowmen/spies/transports...1 k for each level added. So noobies...make 1000 troops for lvl 1, 2000 for lvl 2 forests/lakes etc.
I will complain about the running of this game....and no I won't stop complaining. Every time they add something new, it screws it up. If adding junk it would run just fine.
