This has always baffled me tremendously. Head into a Class Event and look at the rewards…
|Round||Reward 1||Reward 2||Reward 3|
|1||1000 Gold||5 Gems||10 Class XP|
|2||2000 Gold||5 Gems||10 Class XP|
|3||3000 Gold||5 Gems||15 Class XP|
|4||4000 Gold||10 Gems||15 Class XP|
|5||5000 Gold||10 Gems||20 Class XP|
|6||6000 Gold||10 Gems||20 Class XP|
|7||8000 Gold||15 Gems||25 Class XP|
|8||10,000 Gold||Minor Orb of Chaos||30 Class XP|
|Total||39,000 Gold||60 Gems + Minor Orb of Chaos||145 Class XP|
How many Rounds can you complete without spending any gems in the shop? Like 4 maybe tops? So for the people who spend no gems, they get 10k Gold, 25 Gems, and 50 Class XP. So… how do you complete further rounds? Buy the shop Tiers, starting with Tier 1, which costs… 30 Gems. o.O
So you’ve made 25 Gems, now you’re negative 5 after spending 30, but I don’t even think you can complete Round 5 with just the first Tier in the shop – it only gives you 2 sigils! If you get 1 Raven in one of those two fights, that’s enough for only 4/5 of the round, so now you need to buy Tier 2 which is 70 Gems. Okay, now you’ve spent 100 Gems, and you get 3 Sigils from Tier 2. That’s 5 sigils, and now if you’re lucky you’ll get enough ravens to complete 2 full rounds. That bumps you up to completing Round 6.
So now instead of gaining 25 Gems, you’ve lost 55 Gems – spending 100 and getting 45 from Rewards.
So honestly, why even bother giving out Gems as a reward at all? Is this like a credit card or something? It’s a pretty bad credit card, because the tiers all cost more and more, so the percentage of gems that I get back goes further and further down… I mean, Tier 3 to complete Round 7 costs 150 gems but I get 15 gems back.
Edit: and to complete Round 8 for the Minor Orb, you have to purchase Tier 4. Perhaps it’s possible with extremely lucky Ravens, but I think the ravens are pretty well programmed to only show up at specific times. I just finished Reward 7 and I’m going into Round 8 with 7 sigils. Without purchasing Tier 4 (250 Gems), I’d have only 2 sigils. Going into the first fight, I get a Raven – that’s 3 sigils left to do 4 battles. No Raven the second battle. No raven the third battle. No raven the fourth battle. Without Tier 4 I would have ended 1 Sigil short of completing Round 8.
Now… that effectively means I’m spending 500 gems to get 39k Gold, a Minor Orb of Chaos, 145 Class XP (on top of what’s from the shop), and… 60 gems, which doesn’t even feel like a reward, since it’s the same resource I spent to get it.
It’d be like using Gold for Legendary Tasks and one of the rewards is Gold. Wouldn’t make much sense, would it?
