Because it gives them a clear mechanical advantage over the other players. If nearly 100% of the time a cohort will fight along side you, then you are essentially getting a second attack every round or a buffing spell cast on you each round or healing each round, and so on for free.Aloïsius said:And if they earned it, why should they waste a feat on it ? If your character is brillant enough through his actions to win the trust of an army of followers, why should he renounce to learn "great cleave" ?
And why should he have 100 first level mooks rather than 10 2th level buddy ? And why one cohort of level -1 rather than two of level -4 ? You encounter NPC, you interact with them. If you are able to convince them to follow you, they do.
There may be guidelines and advice in the DMG to help the DM keep things balanced, but I really hate the leadership feat and similar stuff.
Why should one player get that for free and not another one? Because he made a good speech? That certainly favors one player type over another one a lot. I know there is at least one type of player who keeps their head down, doesn't say much and would prefer to describe their actions rather than give flowery roleplaying. These players are much more likely to say "My character thanks the men for their help." This likely won't impress the DM and likely won't be noticed.
Whereas the player who says "Thank you gentleman, without your help we would have been killed for sure. I owe you a debt of gratitude. If only I had someone of your skill around all of the time then adventuring would be so much safer." gets the DM thinking and might have the DM offer the services of the NPCs to follow the player around and help them.
And a DM who is thinking only of roleplaying might be inclined to give the player a castle, and a couple hundred guards to protect it, and a castle mage. And in one way that might be fun. In another, that player now has HUGE power than the others don't. The game now uses up more time on him and he becomes more important to the plot.
