I can describe you detailed why this argument is wrong,
but most people wont read a big text, so in (rather) short:
Laming is luck based, not skill based. The argument learn to adept is completly nullifyed by that fact. Sheeps can spawn very far outside, or very close. If one player has a lucky spawn he finds all 8 instantly and can go cross map. If the other player then is unlucky and has his sheeps far out then it can be that he cant find the sheep before his 3th circle around his base, while the enemy can do 1 circle and then be lucky and find the enemy sheeps by luck while he still does his second circle.
The same logic applys to boars.
(and before you say luring back a boar requires skill: every 1300+ player can do that, its no skill, its something normal. And laming has higher impact at higher elos because build orders become more tight)
Also you cant adept, you can only try to minimize the Dmg. Losing 1 boar to a lame makes a Food disadvantage of around 700 food (~350 food lost and 350 gained for the other). You are factually playing from behind by this moment, which means you cant adapt and just try to minimalize the Dmg.
Thats also the reason why in pro play most players go Drush Fc if they get lamed, because a normal feudal Age play is impossible with such a huge disadvantage vs equal players. Hidden Cup 3 Finals are a famous example of laming ruining a hyped Finale. For more detail on this stuff look Nilis Video on why laming should be forbidden: Stealing boars should be banned in (competitive) AoE2 - YouTube
In the end its a non risk action. You lose a bit scout hp for a 700 Food Dark Age advantage. Ofc you can get your second boar together with your first to avoid getting boar lamed, but this would mean you rot away like 100 food, also giving you a big disadvantage only because the existence of the bad mechanic.
And btw 700 Food in Dark age is MASSIVE, because resources are worth more earlier in the Game
All in all Laming is a luck based mechanic, with minimal investment which gives a to big advantage for its minimal risk, which is also highly luck based and by this less competitive.
Ofc it could be fixed with some easy adjustments.
For example ways to fix this laming Problem:
- The starting Scout cant attack Boars like dears. (the fact Scouts cant attack dear and gets killed 1v1 by the boar implies that the Devs 20 years ago thought about this problem, but didnt thought back then that people could lure them back. By this it wasnt intended originally probably)
With this Change you couldnt lame boar/ Dear with the starting scout and would have to either send a Vil or milita. Sending a Vil/ milita would be a bigger investment and by this punish an unsuccesfull lame. A higher risk would justify more its huge potential gain. Huge gains without risk are normaly just unbalanced, huge gains with a meaningful risk are more balanced.
- Sheeps have a much closer max spawning radius. Boar and sheep can spawn in a tile radius with a minimal and maximum distance. Because of this sometimes sheep can spawn so far outside that its hard to find, resulting in situations in which your enemy can find your sheeps before you.
By reducing the max spawn radius Sheep would spawn much closer, making it findable on the first to latest second circle around your base, removing the possibility of not finding it in time. Best solution would probably be to make it as close as your berrys as a max to prevent cheese strats in which people go cross map instantly (which also is a no risk strat, bcs 4 sheep + 2 boar are enough to go feudal, and you can find both boar with sheep scout very consistantly)
→ with these changes laming would still be possible with Vils or a drush, but it would require an investment and justify the potential insanly huge gain by an acctual risk of potential lose in the case of failure. Sheeps couldnt be found by your enemy by luck, but still be stole from under your TC if you miss micro.
Over all it would remove some luck based aspects and make the Game overall more skill based and competitive.
