How to start? Usually that's the hard part. Ok.. let me start with : my english is not top noch, It's my third language so If I do any mistakes you can correct me ( I still have to learn a lot ) or just ignore em
Now.. I've played original dota for 4 years with my friends. Now I stopped playing LoL ( been playin it since beta ) and I also play HoN. So we can say I'm quite and expert when it comes to dota-style games.
When I heard that dota 2 is coming I was first shocked, then also thrilled. Developed by Valve and supported by Icefrog = sounds like a formula for success.
To ensure your success I must add few of my thoughts ( how arrogant I am.. )
If you're and expert what you really want is blacklist. I don't like to play with beginners. Don't get me wrong.. I love to advice em, help em out.. I just don't like em in my game if they don't know what to do.. it's like a business.. if you're good I role with you, if you're not then go find someone whose on your level.
Next thing : leaver protected games ( if player leaves more than 5% of his total games he's marked as a leaver )
Next thing : make sure that graphics won't be that good that 80% of players won't figure out what's happening when ultis starts to fly around.. in addition you can also make team based health bars like LoL has.
And the last and most important thing.. If you stab, kill, pwn someone he or she losses gold when he dies! I hate LoL system which is a complete math failure and is not rewarding enough. I had days when we lost with score 50:20 in our favor = wtfbbqepicfail?
I always loved dota just because kills are rewarding as they should be.. if you pwn someone's ass 3 times his glory days and over and he deserves to pay for his mistakes.. not like in LoL when someone has 1 11 and still posses a threat.. boring, stupid.
I'm really looking forward to DotA2 and I'll meet you on the battlefield. I also stuffed all suggestions here so I won't spam elsewhere.
Have a nice day!
