What would happen?
People on horses rushing through, trying to cap flag.....So no.
Btw, why don't you just make a thread with "yes" and "no" instead of these weird useless answers?
What does this suggestion have to do with "remove ranged" or whatever? 
All attackers is always rushing to capture the flag, and they have to stand near the flag area in order to capture it. they could win if there is no defenders, but it is impossible to do so without the help from the infantry nearby.
also don't forget about friendly infantry, if the horseman want to rush, they have to be careful or else they are bumping all the team mate which can get you kick very soon
there are three main class in CRPG, one is infantry, one is ranged , one is cavalry . Currently infantry and ranged are able to capture the flag while horseman cannot
