Buckle up folks, this is kind of a long one....
There were a number of posts recently about the amount of credits and training droids received in the events after the update. I was certainly one of the people that had some issue with it. However, instead of complaining, I wanted to try to construct an alternate solution. Hopefully, @EA_Jesse
can pass this along to the dev team. I haven't put much thought into the training droid even, but the discussion below, though using profit mining as an example, could easily be tailored to the training droids as well.
There was a drastic reduction in the reward per energy spent. From my best recollection, you could obtain approximately 110,000 credits using 50 energy on Tier II. This translates to about 2200 credits per energy. In the new event, though you can do it multiple times per day, you earn a maximum of 25,200 credits on Tier II for 24 energy, which translates to 1050 credits per energy, a 53% reduction.
Speaking in terms of the mean, it seems a large amount of players indicate they mostly receive the single reward at 8400 credits on Tier 2. This comes out to a measly 350
credits per energy. For the old battles, a mean of 50100 credits per battle at 50 energy, yields a mean of 1002
credits per energy. The percentage drop in the mean reward is about 65%.
The solution I propose is to have a larger multiplier scale, with decreasing probabilities. I've constructed a simulation using a standard, even distribution, random number generator to simulate 100,000 battles using the following reward scale:
Base Tier 1 = 6000 credits
Base Tier 2 = 8400 credits
2X Chance = 50%
3X Chance = 20%
5X Chance = 10%
Over 100,000 battles, the simulation produced the following results:
Number of simulations: 100000
2X Chance: 50%
3X Chance: 20%
5X Chance: 10%
Tier I Credit Award: 6000
Tier II Credit Award: 8400
Number of 1X multipliers: 49816
Number of 2X multipliers: 30236
Number of 3X multipliers: 10007
Number of 5X multipliers: 9941
Average T1 credits obtained per run: 14412
Average T2 credits obtained per run: 20177
From this, we learn that on average, players obtain approximately 20177 credits per battle on Tier 2, equating to an average about 840 credits per energy, with a 10% chance at earning credits at 1750 credits per energy, the mean (as indicated by the results) being still being 1X which comes to 350
credits per energy.
This is still a 16% on average, reduction from the mean of the old Key Card system, but this is balanced by the fact that players can spread out their profit mining throughout the day, using bonus energy, etc. They can do more battles, for more energy, for more reward.
If the numbers above don't suit the idea, they can be tweaked a little, but I urge not to tweak a lot. This type of scale has it all - the element of chance, the risk-reward, the planning through use of energy throughout the day, and the chance of coming quite close to the old system, but on average, not doing quite as well.
Thanks for listening.
Edit: Found some mistakes in the original post, hopefully they are all cleared up now...
