It will satisfy your RPG thirst... for a while (about 20-30 hours until you hit a grind wall or a realization of a huge game flaw which will be explained later in this review). The story is decent. It isn't your cliche cookie cutter story out of a rpg recycling bin, and is good enough to come back for more.
There are lots of quests to do, besides the main story line. In fact, later on, most of the leveling will occur from doing sidequests rather than the main questline. At any time of the day, there will be a global event for you to participate in and earn gold or gear.
There is a guild system and a PVP system. There are 2 types of PVP, which I find pretty ingenious. The first is your regular PVP combat... the more powerful character wins. The second is where the game equalizes the playing field for both characters. In other words, a lvl 50 character vs a lvl 10 haracter will have the same exact stats. This helps newbies become acclimated to the combat system.
THe PVP system is also implemented in a variety of ways. There are 2v2, 3v3, 1v1 equalized PVP duels. There are guild wars. There is a regular 1v1 pvp based on the strength of your character with the AI controlling the opponet.
It's... yes, you guessed it, a godamn pay to win. I have added a few of the top players (ranked in PVP and level) how they attained their current statuses. One told me she paid $1000 (no I counted the zeroes correcly) and the top 2 paid over $2k. The items that are purchasable only with electrum (the in game currency only obtainable through cash) are ultra end game gear that have no level requirement. It takes about a little over $100 USD to gather most of it. (If you want all of the gear, itll be an upwards of 200, excluding armor upgrades which can become very costly.)
What's worse is that this gear is unobtainable anywhere else. You MUST pay. While other games may offer xp boosts, temporary gold gain boosts, or a sweet aesthetic item (like leagues of legends), this game falls within the very definition of pay to win: exclusive ultra gear for those who drop money. (Even Leagues lets you eventually buy champions if you grind hard enough. This game doesn't.)
Sadly, it rewards this type of behavior. Those who pay money, even get to claim more rewards for charging their credit cards.
Consequently, this Pay to Win encouragement totally destroys the guild PVP system out of the water due to the higher tier companies having members who have paid their way to glory.
Aside from the major pay to win flaw, there are other faults with the game. Item customization is very lackluster. While there are color rankings for rarity, there is no INHERENT customization of stats. E.G. Diablo 2 had great item customization in terms of different rare items providing alternate stats to skills and even helped characters gain abilities. For CoS, the rarer the weapon, the stronger the stat. Each item adds one stat. (Yes, just one stat... different pieces of gear add different stats) Item customization is minimal.
SO is the skill system. Over the course of your gameplay your character will receive 5 more skills on top of 3 default ones. You unlock a skill every 5 or 10 levels. When you do unlock a new skill: you are given a choice of 3 different skills that do different higs. You pick one and level it up as you progress. This means, the game has 15 different skills for each character.... as I said, builds are not very diverse. This is not like D2 where there are vastly different builds... a different build varies by 2 skills. THATS IT.
Gameplay is unresponsive and at times, is severely handicappd by lag. Lag is a reocurring problem as there are only 2 servers.. both located in the US.
As you begin playing, the pay to win problems will be masked by the fact that there are just so many evets abvailable for you to do. However, as you begin to gain a decent grasp of what the game offers, you slowly realize the huge, lingering grind wall in front of you. The novelty wears off, and the tedium of grinding begins. Main quests are the same: dungeon clearing with a boss at the end. This is when you start searching for alternate methods of lveling faster, as it begins increasingly difficult to reach the next level.
This is where you fall trapped to the pay to win scheme. You begin to think bout spending real cash on offers such as"brand new ultra gear!" "Tired of being ♥♥♥♥♥? SPend 200 dolars and become awesome!"
Bottom Line: The game is pure pay to win. Unbearably and horribly pay to win. Stay away. It encourages the behaviour with rewards for those who spend money. Not worth your time. Spend your time elsewhere looking for another RPG. Not here.
