SHIELD Combat Readiness Training Marvel War of Heroes introduced a new 'mini event' to substitute for the previous 'assignment' mini events that normally prefaced the large Raid/Shield Events, and its pretty awesome.
Shield Combat Readiness Training allows players to engage in a mini combat free for all to gain shards that can be traded in for rally points, silver, cards for the upcoming event, and even Ability ISOs.
There are three different options for Trading in Shards; 5, 10, 100.
As you move up in number of shards, you gain access to better rewards. Of course the downside is that you still have a pretty substantial chance of getting Rally Points or Silver...neither of which are really sought after.
What's the Best Trade In?
I believe the 10 Shard Trade in is the best value, and here's why. Although 100 Shard trade in doubles the chance of getting Sif and Hercules as well as introduces the ability ISO-8, players still have almost the same chance of getting the rally points and silver as they did before.So, lets say that you have a 2% Chance at Hercules on a 10 shard trade in. Now, you do that trade in 10 times. Since each time its calculated individually it isn't a 20% chance at getting him, but its something around 17% of getting him.
Now, lets say you have 2x the chances on the 100 shard trade in + the Ability ISO chance. So lets say Ability ISO is 2% and 4% Hercules. That's a 6% chance (although 1 of those chances is 2x Hercules) on 1 draw with 100 shards
The absence of Hercules in the 5 shard pack makes them pointless.
Now, if the chance is literally based on the reward selections (which I doubt, but hey, who knows?)
There is a 3/16 chance of getting Hercules or Ability ISO-8 out of the 100 Shard Exchange.
There is a 1/16 chance of getting Hercules out of the 10 Shard Exchange.
There is a 1/11 chance of getting Sif out of the 5 Shard Exchange. (No Hercules. There is a 1/16 chance of getting Sif out of 10 Shard Exchange and 2/16 chance of getting Sif out of 100 Shard Exchange)
This means that over 100 Shards you have 10 1/16 chances at Hercules using the 10 shard exchange, or 3/16 chances of Hercules or Ability ISO on the 100 Shard Exchange. Take your pick (the losing rewards are way better with the 100 Shard Packs unless you get 100k silver like me)
In the end, its your choice, but I prefer my odds with the 10 Shards.
Combat Grades
Interesting. But I fail to get the point of them. They don't give an increase to shards. In fact, as you increase your rank you will be pitted against people with higher rank as well meaning that winning will become more difficult.If there was some final ranking reward or players were given more shards per attack when they increase in rank, I could see a purpose, but in the current inception I don't really see a point. Kind of nice to have a rank though.
