In my opinion, the 3 levels (Beginners, Intermediate, Advanced) were no particularly well geared to their targeted audience user base.
Let’s take for example - the beginners level. A beginner would be expected to have mostly common and uncommon heroes. Very few, if any, rare heroes. These heroes would be in different state of levelling up, but more than likely far from having been maxed out. It should have been a lot easier to complete the full 10 stages of the beginner pane than it was - especially in indeed we were fortunate enough to have rare heroes in their team.
I don’t consider myself a beginner. I participated in the first event, and had then only managed to complete 5 stages. (or was it 4 and I was working on my fifth?). At the time, I was really just a beginner and had only just obtained my first rare hero, Bane).
By now, at this second event I considered myself as somewhat stronger and better equip[ped than a beginner. I had several rare mostly twice ascended heroes, boosted/levelled-up troops, and still only managed to complete 9 stages of the beginners line-up. It was downright discouraging. I did manage to complete 1 stage in the intermediate line-up with only 1 Epic hero in inventory, and managed to get a “participation recognition” in the Advanced line-up for having killed only 2 monsters on the first stage.
Ultimately, all I got for the time I invested in the event was: 3 tokens for daily’s basic summons. That’s it - nothing more! [ The daily quests are far better rewarding than that with nowhere near the same effort to achieve. ]
Ok, that aside - about the event/special summons. About those that are “Limited Time” accessible… how about increasing the chances of receiving one of these special heroes upon getting summoned during the event period? I took advantage of the gems sale twice and obtained 1000 gems each times for these 2 purchase opportunities I was granted. Combined with the few gems I had accumulated by then, I was able to summon 7 heroes. They were ALL rare level heroes. It probably wouldn’t be as frustrating if the Event Summons returned ONLY special limited heroes at EACH different categories - ie. Rare, Epic, Legendary. [Just like when the summon portal is tailored for Fire heroes, choosing to spend and obtain a hero then - we have some expectation to be in a position to be able to strengthen these heroes with either new skills with a new hero we do not have, or by way of levelling up the ones we already have if we get a duplicate.
I couldn’t help but think I’d have better odds in getting hit by lightning, or receiving a bullet playing Russian roulette, than my ever receiving a 4* hero, let alone a special-limited-time hero.
Bottom line is, in my humble opinion, during these events - I should be able to spend my $$ and gems specifically on special limited time hero sets I would not be able to get otherwise, or at least get a much better chance at these special heroes. In my 7 summons, I would liked to have received at the very least 1 - if not 2 - such heroes. Perhaps a way to achieve this would be to offer the option to trigger a summon of say 3 random heroes simultaneously, one of which would be guarantied to be a limited-time hero in this trio, at say: 500 gems a pop?
Another frustrating element during this event was: Why did it have to rely on World Energy to participate? How about setting up a separate Event Energy counter for the purpose so one is not penalised from completing other regular quests that become available during the same time period at the expense of event participation and vice versa? On the matter of Energy, for the sake of fairness, I would also like to suggest the Alliance Energy should be reset to fully loaded for everyone at the time a new titan is unleashed.
I’m throwing ideas at the wall here. Hopefully, some of these will stick. Thus far, I happen to think this is a good game that has the potential to become a great game. That said, If there isn’t a change done soon, I imagine, like several others I’ve read on this forum, I will consider looking for another game as outlet for my free time.
Thank you for taking the time to read my comments.
