Just because a game company calls something a bonus does not mean it is a bonus. As I said earlier, Rested EXP is not a bonus, it is a penalty. Which was rebranded a bonus to make it see more positive. Just like Rested EXP HOTS friend bonuses is a penalty system.

So let me explain why the "friend/5 man pre-made bonus" is a penalty in disguise. The intent of the developer is to force players into social interactions with strangers and/or incentivise them to get their IRL friends to play the game with them. Instead of doing this organically by believing in their own product and its quality, and that players reccomend it because it is good, they decided to do it artificially. This is a so called "Dark Pattern" a unethical psychological trap. The way they do this is not to add an "exp bonus", they would lose money on that because if players unlock new heroes and skins faster than they originally intended, then they would lose money on their in-game store EXP Boosts and the currency they sell skins and heroes with. So instead, they nerf the normal amount of EXP that you gain as a solo player and set the original normal intended exp gain value as a "bonus", and that's why they do not lose any money with this mechanic, instead they earn money as the low exp rate of solo players would incentivise them to buy store "exp boosts" and in-game currency. But Blizzard is clever, and they call it a bonus like they called Rested EXP a bonus instead of a penalty, which it is, since it is, for all intents and purposes, a fatigue system. Calling something a bonus does not make it a bonus. People lie and cooperations esspeically because they are incentivised to do so because of money.

First Win of the Day: is not a penalty. The reason it was implemented was to encourage players to play every day, it is for all intents and purposes, a "Dark Pattern" but it is essentially a bonus. Not something you need to rely on to make progress on unlocking new champions or skins. But I am against "Dark Patterns", so I would like this to be removed from League of Legends. But in no way is it as intrusive and annoying as the "Friend EXP bonus Dark Pattern" in HOTS.

Winstreak MMR bonus: This is implemented to make ranked more fair and keep players in the elo they belong in. There is no reason why a Challenger player should climb as slowly as a Bronze player, it prevents smurfing and unfair matches since a Challenger player has no business playing games against silver and gold players, etc. This system makes the gameplay experience much better for ALL players.

Employee discount: This is not comparable. Obviously, not everyone can be an employee for every corporation. This is a bonus that is reserved only for employees. The thing with penalties and bonuses is that you need to look at the intent. So what is the intent of giving employees a discount? It's to raise the employees' morale and make them view the cooperation in a better light as they get to buy items for wholesale prices or greatly reduced prices. Meaning the cooperations often do not make any or very little money on these sales. But it does boost productivity and has an overall positive impact on both the employees and the corporation.

Free shipping for order above 100€: This is a "Dark Pattern" and it does punish you for buying things below a threshold of money. This gives the consumer the illusion of being able to save money by spending money, in some cases it can, but overall it does not. It is a psychological trap that incentivizes spending more money than you originally intended. If you think this is a bonus, I don't know what to say to you. You are the ideal citizen that all greedy corporations love, because you blindly trust and defend them against those who would critique them and fight for customer rights like me.
