More specific information on T1 and T2 gear progression and Island material rewards

As a hardcore veteran who likes to min-max, I would like to know what kind of changes have been made to tier 1 and tier 2 gear upgrading compared to how it was in CBT. It was stated in January Update that it has been balanced, but it should not slow us down. Does that mean, we will be able to breeze through tier 1 and tier 2 with ease as it was in CBT or its going to take longer?

Also a lot of Island quest rewards have had ‘catch up mechanic’ rewards, in terms of materials, engravings, pirate coins and other goodies. Are these rewards staying the same as they were on CBT, or has it been removed / adjusted where we will still get same rewards but in less quantities?

Sorry for ping and hopefully I can get a clear answer on that. @Roxx

Guess no info till patch notes.
