First off, I think of polearms in general as specialty weapons that all have a niche to fill. Becs for tight areas were you need to swing, English bills for long ranged combat with more than one direction, awlpikes for murdering horses, and pikes/longspears for long distance warfare along with "you must block down or get hit". In NA I believe polearms are much more viable being that in a 40v40 server there is always a group of 25 on each team that whomp sometime in the round. The way I am hearing it is that EU is mostly skirmishing people, and of course, pikes should not be viable, let alone any polearm, in any skirmishing situation.
An example of pikes being used effectively is on NA a few nights ago when there were about 7 or 8 ravens on. they had 3 pikers, 1 hoplite and the rest strength sheilders with things like heavy battle axes or military sickles. If you were not blocking down you were getting stabbed, if you were blocking down you got mobbed by fast hard hitting shielders. The situation was helpless and if you got one kill on them you were lucky.
Pikes and longspears get used very well in NA, perhaps you just need to find the right teammates in the server or get your friends to play more cohesively in EU. Pikes, let alone long spears, should be left alone and be kept as-is in my opinion.
