Myth Buster: Speed
However due to these distinct advantages of speed, I think there are alot of people who gets caught up in the hype and put blind faith into it. I see all the time on various world chats, when someone ask what stat is best to put your points in, there is a flood of people (alot of them are newbies themselves) giving out a simple "all into speed" answer. I understand that they have the best of intentions but this can be quite misleading or even disastrous for a new player who doesn't have an in-depth understanding of the Haypi battle system.
I believe this blind faith on Speed by the masses are perhaps driven by experienced high level players who sworn by Speed, while this is true in one sense, Speed isn't for everyone. Unless you're at a high level with enough attribute points to take full advantage of high speed, then sometimes going all Speed isn't the most ideal choice.
If you are low in level (level 13 and under), chances are the best combination for your army is the inf/cats setup, this is the most efficient setup for fort farming and the easiest to command in battle. Cats who gets a first strik in battle is a great advantage for anyone, but it is certainly not something you can put your complete faith in at low level. When you are battling an opponent of similar level with a similar army, the player who goes all speed will be beaten by someone who goes all attack, or all defense, or a balanced stat.
Example scenario:
2 level 10 players, Player A with all Speed at 82, Player B with all Attack at 100 Attack and 2 more points to put in anything else. Both have mid level equipment that gives between 10-15 points boost for every stats and mid level techs for both, (assuming similar level range tech)
Player A is attacking with 3000/0/100/1000
Player B is defending with 2000/150/0/1000
Defense: 5 low level traps
Forget the supporting army, the true battle is fought between cats (some experienced generals may try to pull some moves with the other units but we won't worry about that here).
Turn 1:
Player A advance cats, hold inf and arch
Player B advance cats, hold inf and cav
Turn 2:
Player A advance cats,
Player B advance cats,
Player A's 1000 cats makes first strike takes out roughly 450 enemy cats, Player B's 550 remaining cats retaliation attack, destroy 500 cats.
Player B's 550 cats makes attack, destroy remaining 500 cats.
After turn 2,
Player A have 3000/0/100/0 remaining
Player B have 2000/150/0/550 remaining. It is clear that Player B will be the eventual winner. His cats will have the abiilty to take out close to 1500 inf in one turn, if Player A times his advance he may be able to land one more attack on Player B's cats with his archers, but the most 100 archers can take out in this instance is 10 cats before getting wiped out by retaliation attack.
Note: This is an extremely rough simulation and the figure will vary depends on the setup of the individual player.
The retaliation attack is often something most beginners do not consider when they estimate a battle (even alot of experienced level players tend to miscalculate).
To put it simply, if you want to go all speed, you need to make sure you can finish the job, for a cats army, high speed needs to be coupled with high attack for maximum effectiveness and high defense are needed for a cavs army.
Low level players who puts all their stats in Speed will also have a noticeably harder time when attacking forts and oasis. This means the Speedy players require a much larger number of cats to take on the same level fort/oasis compare to another player with high attack. Which means a noticeably slower progress at the beginning as resources will be harder to accumulate.
In conclusion (and to stop this long essay

So I believe that the best advise is to make informed decisions, understand the consequence and what you're looking to achieve before distributing your attribute points.
P.S. I am not advocating low Speed, Speed is still the most important factor in 90% of the battles between high levels, but when everyone use/has max speed, that's when other setups and tactics needs to be considered.
