You wont notice it at 1st few months, but as soon as you play on 6th month onward, you will really bored because of that, NO BLITZ/RAID system killed this fun despite you already have S-Rank on ALL, you still need doing it MANUAL which is really stupid idea.
You already have 12 GB game and still dont have BLITZ/RAID system??? What kind of Old-School are you??? Every game right now had it on 1st day release since 2015 onward and your game is already 4 years old and did not improved at all but instead adding more and more skins with ships BUT never improved USER EXPERIENCE at all.
This is the biggest reason why players quit this game despite it was friendly, but they burnt out as time goes even on AUTO mode, your AI is so DUNCE that they just diving to enemies and damaged them badly and you are taking control again.
Please do review some suggestions that will improved User Experience on player
1. Add Blitz/Raid system on any battle that already have S-Rank on Campaign and Events, this will reduce time needed to grind significantly and more time can be spent on other tasks.
2. Increase Dock Limit (Ship Storage) into 200-250 instead of 100 at start of the game, many players complaint about how small the Dock is and you really need another 200 Gems which is very expensive to spend. Make Dock expansion cost reduced to 100 Gems/10 space for better storage management.
3.Let us have Gem rewards on Daily and Weekly missions where if you can complete ALL of them, you will rewarded small amount of it like 2-3 gems daily and 15 gems weekly. Its not that much, but it will give us more things to do on long-term play instead of MEASLY rewards that can be forgotten everytime.
4. META Events are not needed lenghty, just make it into 1 months instead of 2 months and convert the points into Achievements like how many damage you deal to Boss and helping others will give you another points too. I really bored doing same tasks on every META and I just always missed few days because of too much tasks to do everyday, make it simple and less burden.
5. Siren Monthly reset are really not necessary especially on Map Zone reset where you need to rewind all AREA once again, just give us BOSS/FLAGSHIP only to clear them instead of beating all small enemies again, can you imagine doing a zone where you need to beat 10-15 units every single time on monthly where you can skip to BOSS fight only??? This tasks become tall order to play.
6. Shipyard EXP requirement should be reworked because in order to Collect EXP, you can only used certain Faction/Group which is fine, but at least make it count as ENTIRE FLEET instead of MAIN or VANGUARD only. It was tedious to collect 1 Million EXP and another 2 Million EXP after 3 days passed, even if you have 2x EXP/Resource used, your ships will take heavy toll because their moral get abused too much and it caused Upset/Mutiny if overdoing it. This ship also not very good too IMO because there are more ships that has way better than Priority ships we have right now and they only good against SIREN, outside of that, it just GARBAGE and barely useful.
7. Ship Build should have lists of units that can be gained prior or after updates to keep track which units can be gained from there and which is Event-only (disappear until rerun happened again. Also, any ships that is newly added should be highlighted with New until next update happened.
There is more to say, but most of them are just minor things and these are the most discussed in threads and comments section right now.
I dont want this game become a chore that burnt the players on long-term, but at least make it less burden to everyone including newcomers.
