TESO will do quite well in my mind but there are a few problems that I feel could develop into gamebreakers.......
1) Guilds are VERY restrictive right now if you dont have at least 10 members u cannot use the guild bank for example....this rules out the players who like to have their own alt guild putting restrictions like this on guilds severely inhibits alt play
2) Character Bank this is a HUGE one, right now you only have ONE bank shared across all toons and it is limited to like 100 slots, this again greatly discourages alt playing which is a HUGE part of any MMORPG crafting materials alone are over 100 items, in the beta I was constantly having to delete or sell crafting materials and other stuff I had no desire to get rid of because my bags were full. then I created a new character and started gathering and when I went to store my stuff in the bank I found out it was ONE bank for the entire account....this is a HUGE NONO, there is nothing wrong with a nice big SHARED BANK per account but we ALSO need a nice big bank per toon, otherwise like I said ur hurting the longevity of the game
3)challenge quests and puzzle quests, these are amazing fun but to be honest there isnt anywheres near enough of them from what I have experienced so far I think it was a total of 3 in the entire 1 - 17 area I was also amazed at the amount of ppl that couldnt figure them out even though the answer was literally right in front of their faces, do more of these they are fun
4) fame/infamy man this is a HUGE hit in the game, its nice that we have our own boxes and crates to search through all over the world but one of the BIG things about TES worlds is the interaction between the player and the guards if the player decided to take an evil route as in stealing from the towns people or killing npc's etc I hope this gets changed soon, right now there is no penalties at all for bad behaviour, MY character is a mage assassin she plays the hero and helps the people who are in trouble out and never asks for reward from any of them BUT she does like the fun of stealing from them once in a while and the risk that goes with it
5)the PVP of cyrodiil is great fun as I have said before, there is nothing wrong with it as long as it remains a side dish in the world of TESO, but the moment you focus on the RVR PVP as the MAIN DISH at endgame, that is where the problem WILL arise....there are around 10 million Elder Scrolls fans world wide looking at this game and there are about 250k DAOC,Warhammer,GW2 fans looking at this game, it only makes sense to cater to the majority rather than the minority I am pretty sure you realize this but if you dont realize it yet lets hope you do soon.
other than that quite honestly the game is amazing in my mind, I AM very thankful you allowed me to be part of all your beta tests, and I look forward to either the next Beta Test Weekend or maybe an Ongoing Beta test if you decide to start one up, if not then I will hopefully see you all when the game goes live.
P.S number 1 and number 2 are the only ones I feel are gamebreaking because the current system REALLY hurts ppl who love to craft and play alts
BTW to those of you who love crafting I hope you read this post and help keep it alive in the hopes it will get noticed, please refrain from flaming and trolling in this post as I would really like to see it brought to the attention of the people that really matter.
