Why would you change algo. This is not good decision. First generation of ASIC machines will go to primary coins like PASCAL, after 2nd generation of stronger ASIC early miners with weak machines will move to PASCAL Lite and other coins supported by that ASIC. Also those who have just one or two ASIC miners won't stand a chance on PASCAL, so again they will start to mine PASCAL Lite to at least try to recover their investment.
Initially ASIC machines will make major influence on the coins price who will drop but once stabilized with ASIC hash power it will ensure more investments on the market.
Keeping this algo will show support for early GPU miner who collected PASCAL Lite over the time. After all everything will end up eventually that with strongest ASIC miner you won't be able to mine more than 1 PASL per day. If we remember what happened with scrypt ASIC miners then all is easy to understand. Now on every single scrypt coin you have high diff because people have lot of unusable ASIC machines who can't do much on Litecoin or any other popular scrypt coin but they didn't trow them away. They put them on first scyrpt coin they found who is not even listed on the market thinking maybe something will happen with it. On other side ASIC sellers much invest portion of money earned to rise the price of coin or algo they support to ensure that their ASIC will be sold in the future. After all of this PASCAL will worth up to 300USD, PASL maybe 50USD and then you will see lot of new coins with this algo. Again, from history, I have mined lot of scrypt coins when diff was lower than 1, now on same coins mined by ASIC diff is more than 300, price increased a lot over the time. Complete situation with those ASIC machines will be only bad for GPU miners who were here only for quick profit selling instantly what they mine but those are not real supporters of this project. Those who mined and hold are and they will benefit from this a lot. So think twice what is smart to do. PASL is 2nd coin in the line of coins supporting this algo, don't lose that place. Comparing Dash(Darkcoin) and his followers using same algo you can see ASIC influence and price ranges/hash rate they had over the time to the situation we have now with them when all is crystal clear about stuff I m saying. My advice is to don't touch anything but patiently wait.
As far as I Know PASCAL will also switch to a new algo.
The problem with the ASICs is primarily centralization. Someone with a few machines can easily 51% attack the network. With the speeds that they pose, GPU miners won't be able to keep up. We want to make the coin possible to mine with a GPU again.
I will discuss your thoughts with the dev and see what they say either way.
