Could it be better? Definitely but it's not that difficult to navigate.
I dunno if you use a lot of software or not but the new website is definitely not user friendly, the whole interface maybe more suitable to touchscreen but even that, it's horrendous to navigate to the things you want.
I myself uses a whole spectrum of softwares and has no less than 5 different bank accounts, OCBC has the best UI of them. The software I interact with on a daily basis is After effects, Photoshop, 3ds max, Zbrush. Photoshop is almost the most simple of them all.
One doesn't design a website to be more difficult to find things than before.
Try looking for the daily$... I just wanna see how much I have, cannot find it... Last time it was just at the home screen right hand side.
Now to find this daily$ you have to go to your credit card, go to statement, go to the dropdown of statement type, look for cash rebate unbilled to see how much daily$ you have.
