HAHAHAHAHA
1) 1h/shield combo is fine and perfectly capable of avoiding being spammed to death by 2h/pole. That is a case of PEBKAC, so get better
2) There are 95-100 speed shields that last for incredibly long times in combat - IF you put the damn thing away vs a bonus vs shields weapon (axes, morningstar, etc). L2Manual block and don't be afraid of 1h/no shield.
3) Plenty of us use 1h/shield because we like the style and do exceedingly well with it. ManOfWar, Huey, Dan (pre-2her gen), Cyranule (Pre-2her gen) for example. Not to sound like I'm masturfapping, but I Myself tend to do notably well with 1h/shield I think, though you'd have to ask others that play with me often for an unbiased opinion. (I have a 1h/2h hybrid and a 1h/polearm hoplite hybrid I swap between and both use their 1hers quite a bit)
Overall, this really is a case of PEBKAC and you needing to work on your melee more.
My point still holds that 95% of the best players all roll 2h/pa, that alone shows that they need balancing.
This is because they're the BEST PLAYERS and 2h/polearm is usually more challenging/fun (which are usually one in the same for the better players). Some of those better players also roll around with crap weapons like 1h practice swords, long daggers, pitchforks and such just for the luls and STILL top the boards.
