We should be expecting more from Ethereum in the near future because it may seems like everything about the coin seems not being attractive as we have expected, but things have to do with time and season regarding the performance of some of this cryptocurrencies, because it will still make a new all time high soon only for those who were able to wait patiently in expectations for it to perform outs tritely again.
What makes you think it is not as attractive as we expected? It is the second-largest cryptocurrency in the market by market capitalization, it is the second-most trusted cryptocurrency in the market after Bitcoin, and it is the largest altcoin that has ever existed in the market, and besides all these things, it has been holding this position for a very very long time, so I don't agree with what you said.
Transaction fees of its blockchain might cause problems sometimes, but the developers are always working to fix those issues by implementing new versions and forks, and I'm pretty sure that ETH is going to perform extremely well in the upcoming bull run.
