No flags on siege makes sense, there is 1 flag in the casttle, ok.
But what about just the icon of the batallion's flag flashing over the screamer's head, to say: HEY! i going to attack! (icon: HAND and SWORD), defend here! (icon: SHIELD), follow me! (icon: ARROW), etc...
Yep, i kown we have taunts but screams seems to disturb ppl. CRPG is just great, it's just need more TEAMWORK (and new items...) and maybe this encourage teamwork in sieges.
P.S: just your team can see that flashing icon.
P.S2: an icon to say SORRY! (shit happens) and a LOL icon (hardly).
P.S3: a gj! flashing icon...
