This is offensive. I put in 100% work and could not achieve 100% results (fully evolved building). I am not new. I know how to play.If you failed to make all 9 artifacts in the event, then it's because YOU failed - not Inno...
There has not been a single evo building event where it's been a 'pay-to-win' wall to complete all 9 evos for free. The newer 'shuffle board' events are so beyond childishly easy especially, that you have to actually go out of your way to purposefully fail!
...for example, I was so unimpressed by how gak-awful the May event building was, that my E-world city didn't even bother to finish the quest line! I was about 7-8 quests shy by the end, and I still even won the 2nd copy of the Lv1 base building!lol.
Completing 9 artifacts is simple, even if you're a 100% free to play player;
1. Complete. The. Entire. Quest. Line.
Inno has watered these down to the point that even Ch1 cities can do this. If you're not able to finish the entire quest line, then you may need to re-evaluate your city & how you're playing the game.
2. Pick up at least 16-18 incidents per day.
As these fall roughly at a rate of 1/hr, and don't max out until 6 have been left uncollected about your city, it's fairly simple to keep things mostly cleaned up. Even with a steady job/family, a few bathroom breaks are all the time required to at least sweep about the city outskirts for incidents.
3. Use Gems of Knowledge/Platinum Leaf, etc... resources to always choose the most 'grand prize' efficient choices
In any of the '3 rotating chests' formats, these on-line resources do all the hard math for the rest of us, and picking the right chests to maximise the number of grand prizes received is as simply as just reading a basic chart & picking the smallest number.
The shuffle board style events are even easier! Just use/save up your 'reveal 2' & 'x2' bonuses to find and/or double up the bonus grand prize pts!
The only mini game here where things might actually get 'difficult', is the Halloween event, as that requires knowing how to best utilise the 3 tools to most efficiently clear out the mist.
4. Find a Fellowship that can complete the Fellowship Adventures.
Now, even *if* you fail to win all 9 artifacts during the event itself, as long as you're in a fellowship that can complete 1 of the 3 paths on each stage of the FA's, you'll gain 2 additional artifacts!
Any fellowship that at least has a pulse vs. 15-20+ abandoned cities can easily complete 1 path on each stage, as we have a little over 6 days in which to do so!
...now, if even still, you're routinely only gaining 4-6 artifacts per event, then honestly, you're simply not playing the game actively at all and thus, it isn't INNO's fault that you're choosing to spend time & energy on other priorities.
Just like in school, if you only complete 50% of the work, you'll be lucky to achieve a passing grade. Events are no different; if you're only putting in 50-75% of the requirements, then don't expect 100% results.
There is definitely a luck factor involved, also. I missed almost no currency drops (only a couple times during the entire event did I collect six at once, and I do not believe it was waiting long for me to free it up to drop more) and quest-locked long before end of event (finished quest lines, of course). I made what I believed to be the best choices on the rings. There is literally nothing I could have done other than purchase to result better. What made the difference, I fully believe, was the bonus currency (or lack thereof) from the rings. I hardly got any in either of my cities and I am confident that if I had hit those a little more, it would have been enough to get my ninth artifact. Quest+fallen+daily currency was simply not enough. I wasn't as lucky as the last event and it cost me.
I think I understand what your actual point is (regarding people not fully doing the event and still expecting the complete building). However, suggesting that failure to complete the building is due to failure to put in the work is wrong. Not only that, you seem to also suggest that a complete building is possible even without doing all the work, implying the failures are idiots (no, you did not use that word, but it sure felt that way).
Each of my cities is in a great FS and I will have no problem finishing it, but that is beside the point. It is good that FA artifacts are there to fall back on, but we shouldn't have to need them, especially for players who did put in the work.
