When the Alteil team overhauled their level up system it was met with a lot of positive response. However, I still think there can be grounds made to further improve it, especially with more cards than ever. This can help Iczers across all the gaps from free players (quicker access to cards) to big spenders (more gran for special events, new releases). The idea is that this can help retain players at a higher rate.
My proposed expansion of the idea keeps current level ups the same but adds the following
1. All current levels that end in a 5 (45, 55, etc) that do not have a current level up gain the following: Random 3 stars, with small chance for 4 stars
2. All remaining odd numbered levels that do not have a level up provide a random 1 star with a small chance for a 2 star
3. All remaining even numbered levels that do not have a level up provide a random 2 star with a small chance for a 3 star
The above level ups apply up to level 100. Beyond level 100 refer to the below chart
Every 5th level beyond 100 (105, 115, etc) gives a random 4 star with a small chance for a 5 star
Levels that end in 3 and 8 (103, 108, 113, 118, etc) give a random 3 star with a small chance for a 4 star
Levels that end in 1, 4, 7 give a random 1 star with a slight chance of a 2 star and a very small chance of a 3 star
Levels that end in 2, 6, 9 give a random 2 star with a small chance of a 3 star
Obviously, the above star rarities can be tweaked but the main principle is to reward players for every level they reach. Hitting those points where it is 10 levels can be very draining on the emotion of climbing up a mountain to the next reward, especially when XP levels hit 500 XP/level.
In addition the GM’s seem to be pushing point cards lately. I propose that point cards be given out at every level, automatically, in addition to level up cards. The amount of point cards given at each level depend on the amount of XP needed to level up. In short, for every 100 XP needed for a level you get 1 point card (IE: 100 XP needed to level up you get 1 point card, 200 XP 2 point cards, etc.)
