Okay, I think I should say something to this, as I probably am one of the most experienced 1h/boarders here (I started my career in August '10 as 1h/boarder and only interrupted it for 3 generations as cav/pole and archer/2h).
FF prone - dealing and receiving. Mostly due to the shorter nature of the weapons.
That depends on the playstyle. If you're a "CHARGE!"-player, always in the first row of battleformations, then it's clear as the day that you will get some teamslashes from time to time. That's what you have, on a Str build, your armor for. As to dealing FF... that is entirely your problem of not watching where you swing. It happens to everybody, especially with unbalanced Axes, but one can still watch his surroundings and act accordingly
Tunnel vision - the need to maintain a shield in front of the current opponent can easily lead to tunnel vision. Remapping of the look around key may help.
I have that problem sometimes too. I see a group of enemies, don't know where my teammates are, rely on my shield and charge straight on - dead. Again this is a problem of each his own. You'll see you seldomly have the time to use that "look-around-yourself"key as you're heavily engaged into battle.
RMBitis - finger locked on RMB can lead to stubborn releases.
What do you mean with this? Enemy releases or your own? I'm finding myself more often than not waiting until the enemy connects with my shield before I strike back. Mostly because they feint a lot and i might release RMB at the wrong moment.
Getting swarmed. I find it easier to deal with multiple opponents with anything BUT sword and board. I am not sure if turn speed is slowed when holding RMB, it used to be.
That's the problem of charging head on completely alone. Enemies see "Oh, big shield guy, let's gank him". Boom, dead. Either tactical retreat or keep on charging into the middle of the crowd and hope for a lot of TKs on enemyside (always rofling when there're like 3 TKs around me while I'm moshing through the crowd. xD)
Crush Through - sure you CAN deal with it when one versus one, how often does that hapen? Possibly the silliest mechanic ever.
One solution: Release RMB and run the hell out of there. Or spam the Maulers and run circles around them.
Back pedallers. You may have to content yourself with getting one strike in and maintaining position, or risk getting swarmed due to over pursuit.
Pff. I'll wait for them and literally tap my feet until they decide to come near again. Might slash another ernemy until then.
'Spammers' the guys who don't give you a chance to strike back. Really need to discover their timing, unfortunately, this can lead to a long delay.
What was that saying from Phyrex? Spam happens cause you either fail to spam yourself, have a fail build or just plain suck. Chambering, running circles around 'em, spam back.
Delay - this can be good or dreadful. It can take a long time at times to kill someone, which ties you up.
See RMBitis.
ROLES
Roadblock. Turtle in heavy armour, strike only when necessary, but be a bulwark for your team mates to work around. Can infuriate some people.
I love playing that one. Charge straight into the crowd, leave a path of havoc behind yourself from the teammatesand be the happy lone man standing afterwards cause you backslashed a lot of people. xD0
Guard. Guard an archer or group of ranged, intercept incoming; essentially watching their backs.
I only play this with clanmates. Otherwise either Archers fail at positioning or they don't watch themselves enough.
daggger and buckler assasin, with light armor.
Never done this, not my playstyle.
Pushing the front.
See Roadblock.
Advancing on archers. This is kind of key; hiding behind the two handers is common, but improper. Of course, those speedy bastards do not wait for you.
Meh, hate archers when I charge them cause they always outrun me. Flanking them helps though, just out of their periphal vision.
Ability to switch roles / mode
That's why I love 1h/board. It just gives so many opportunities.
