This is primarily because both units have Longbows start with a max range of 22 and skirmishers 20, so shouldn't it be reasonable that autoattack for longbows is at least increased to 18. Skirmishers have so much of an advantage doing hit and run attacks that it isn't even funny and this slight change may make British more feasible. This does not even take into account that once improved longbows are researched, the autoattack value still is not changed - sigh. 26 range and line of sight and will still just stand there when enemy is 17 away - hmmm... I do not mean to be derogatory. There are many things I love about this game now that I have played for a while. I think it has more staying power than even AOM did/does as long as ES does some attempt at balance changes every three months or less.
