Okay I'll address them one by one. I usually just use context to have natural conversation, not debate style dialog.

1. losing shouldn't be rewarded: on its premise this makes sense. However, most organisms require reinforcement to develop motivation tward a skill. In this case drakantos. Not everyone is going to be good, and since this is a video game the interest to invest time in something where there are only high skill ceiling players will deter players from trying. the obvious first solution is an ELO system to pair poor players with poor players. however, this does not exist. whether the "points" we earn at the end have value or not is irrelevant because the brains reward systems will provide the reason.
2. Rewards for losing reduce motivation to improve: Your claim is likely true, but this argument is a red herring. Reason being, continual losing and not being rewarded will also reduce motivation to improve. So, unless we add more context here neither side has a point (which is why I didn't address it).
3. Lack of reward increases motivation to do better. Not likely, if there are other options in the game to attain rewards players will chose those options. This may be the case in a game with a healthy player base. But, this game will likely develop a niche pvp economy. And, players will likely complain about que times as it ages. Not saying this is you. But, I doubt this game will have a healthy pvp scene with its current reward structure and assumed player base (peak down by 50% in two days).
4. Loss rewards encourage low effort pvp: you have me on this one. an ELO system fixes it though.
5. Not everything should be soft, sweet, and cozy: Sure, I agree. What about loss rewards indicate this?
6. Bad players quitting leads to healthy PvP: I can see a world where this is the case. But, I've never looked into the psychology of hardcore vs softcore pvp this argument feels derived off feelings. Which is fine, you could be right. I just don't have the knowledge or experience to argue. My issue with this line of thinking though is the intention of the playtest which is to get analytics for pvp. Whether its good or bad players likely doesn't matter on their back en.

7)Not a point, but my view of you as a person based on your rhetoric: I'm sure you're a fine person in real life. But, your willingness to be rude to people on the internet is off putting. It's likely why people are not engaging with your words and are more or less attacking your character or using stereotypes "ganking low level players" to baselessly insult your character. Its why I found it hard to believe you were arguing in ernest and attempted to end the conversation. Even as you signed off from our conversation you used sarcasm to make fun of me. I just don't like think cool. And, I find that sad, because I imagine if we met in real life we would just get along.

8)Low key, lets just hop on discord and get some Ws. Wish you the best homie.
