POSITIVES:
- A game you quite literally can't finish
- Extreme in-depth team building
- Extreme in-depth equipment system
- Passive income from PVP
- So many units I literally couldn't count 'em
- Various types of content, frequent events


DOWNSIDES:
- Abysmal RNG
- Devs can't communicate even if they had a gun to their back
- The PC port is an actual abomination
- Auto-equip system was designed by a blind monk who's never held a weapon
- Some content requires an EXTREME amount of premium units
- Top PVP players are just rich people
- You can skip skill animations but you have to waste time loking at Limit Bursts
- Very P2W oriented content
- Main Story only has 40 chapters as of right now and the rewards are frankly underwhelming. Only the gems are worth the hassle.
- Grindier than ♥♥♥♥♥♥♥ Black Desert Online

Ironically enough I'm not struggling with the low rates, etc..
F2P player here. Been playing the game for a solid bunch of years. Game's given away Vindicators, Upgrade Potions, 5* relevant equipments, etc..
I'm assuming the review bombing is coming from people who have overinvested in a gambling system and are somehow surprised when they find out they're losing $$$. Do you complain to the casino hosts as well when you lose?

Premium units are indeed rare. Although, with the right knowledge, equipment and combinations, you can clear most of the available content with free units/units you'll obtain for free over the long run.

Based on personal experience: 0$ spent, I have 22 units that would be defined as "premium".
Just look up the pull rates and keep your expectations down. The happiest player is the clueless one.

If I'm being fair though, it's far from the "unfair" game being described in most reviews. It's just one of these games you play daily and you occasionally get bombed by RNG. (I've had a few pulls where there were 2 PREMIUM UNITS IN ONE).

Engaging characters, intriguing plot, but lacks unique mechanics.

Strap in folks, because Valkyrie Connect is as unpredictable as my ex's mood swings! It's like opening up a box of chocolates, but instead of chocolates, it's a bunch of Norse gods brawling. Five stars for sheer audacity!
