Read from forum where alot get ban due to purchase some illegal/hacked points.
1. There are always risk if you trying to cheat. There wont be any risk at all if you are asking bout foreign players getting ban
2. Can but majority there wont understand you
3. Before thinking of buying cash, first you need to get you account verified, Only verified member can reload M points
4. Hardly can find any pros, beside you wont get ban easily even cheating
5. Update roughly same as KR, but you wont get the latest unit from KR in TW. Every month there will be a dream cap featuring a new S rank, which is the S rank that released in KR around half year ago, eg this month TW dream cap is Xbone X2. After being released in dream cap, that particular S rank will need to wait maybe another half year time to be available in mix plan, eg this month M plan is NTD and G plan is V2A, where NTD was released around October last year and V2A around November last year. SS is forever locked in TW for the moment, where only purchasable during some event with coins/cash
6. You wont need to tiptoe in TW server as compare to KR, but you wont able to enjoy all latest MS as like in KR, as well as latest game features.
