In the early game, Gauls have a lot of advantages due to their Cranny Bonus, and Trapper, and cheap phalanx.
The trapper, especially is annoying to everyone, including other Gaul players, and many players fear the attacking Gauls, due to their trapper.
I think, it it would it be more enjoyable in gameplay if Travian HQ removed both the
(1) Trapper, and
(2) Cranny Bonus (so that the cranny is exactly the same as the other tribes) --
to encourage a more aggressive, free-flowing, PvP attacking playerstyle for all tribes, and also due to the reduction of the playerbase across all servers.
It would be fun to see some Gaul-on-Gaul action, or Roman-on-Gaul, or even Egyptian-on-Gaul, in the early game.
I guess they could balance the removal of both Trapper, and Cranny Bonus, if they reduced the cost of Swordsman to total:510 resources (ie 25 resources less), and reduce cost of TTs to total: 1060 (ie 30 resources less), but keep all other stats exactly the same (training time, offense/defense stats). It'll encourage some Gaul players to go swordsmen first, risking them of being attacked/countered by other cavalry, and the reduction of cost of TTs is necessary due to removal of all resource-saving buildings to Gauls.
And in terms of a Gaul unique building, maybe it would be great if Gauls did not have any tribal-specific building as Travian HQ, does not seem interested in adding/or changing buildings for this tribe. Every other tribe has a mid- to late- game building, but not so for Gauls.
