Will say a few things that don't necessarily strike to the points you brought up but should answer concerns you have regarding the event shop and earning of event points in general;
- There are plans to rebalance the event shop with items that are more worthwhile to acquire; i.e weapons that can compete with donation weapons and legendary weapons given the difficulty in acquiring event points, as you mentioned, and the already very high prices for items that are technically weaker than the equivalent donation weapons when converting to coins. Event points can be considered much more valuable than coins; getting 100 event points, while convertable to 200 coins, is a lot harder to get than 200 coins.
- A recent discussion about the nature of winning rarity in events lead to the idea that we can multiply everything event-point-related by a number like 10; if you had 13 event points, you would now have 130, and the 100 event point weapons in the shop would be 1000 instead. This enables sending effectively fractions of points, like sending 1-2 event points as a participation reward (which would be 1/10 or 1/5 of an event point), thus rewarding everyone that plays and not just the winner. Perhaps the second place can also be rewarded with 5, which is half an event point. However, a system like this would make it much more difficult for the event team to send points to everyone in the room, essentially requiring a sort of command to automatically send to everyone in the room which is non-trivial to implement.
